Abstract

A laser small arms transmitter (SAT) which may be affixed to the stock of a rifle such as an M16 used by a soldier in training with a multiple integrated laser engagement system (MILES). The transmitter includes a housing assembly having a forward end with a window through which the beam of a laser diode is emitted. A pair of optical wedges are positioned inside the housing assembly between the laser diode and the window. The optical wedges are supported for independent rotation about a common optical axis for steering the laser beam. An alignment head may be physically mated to the rearward end of the housing assembly for driving a pair of shafts to rotate the optical wedges in the alignment of the transmitter so that a soldier can accurately hit a target once he or she has located the target in the conventional sights of the rifle. The laser transmitter may also include a sensor for detecting the firing of a blank cartridge, a fire LED mounted inside the housing for producing an optical signal to indicate to the alignment head that the laser diode has been energized, and an inductive switch connected to a power circuit and actuable by an induction coil in the alignment head to energize the laser diode.

Description

Description: TECHNICAL FIELD The present invention relates to training equipment for the military, and more particularly to a laser transmitter mounted on a rifle used by soldiers in combat exercises.

BACKGROUND ART The US military has long been involved in multiple integrated laser engagement systems (MILES).
soldiers have been trained using an engagement system.
Laser transmitter for small arms (SAT: laser small)
The arms transmitter is fixed to the stock of a rifle such as an M-16 rifle. Each soldier attaches a sensor to the helmet and shoulder belt to detect the hit of the laser "bullet". The soldier triggers a rifle and fires a blank simulating the actual firing of a bullet. An audio sensor activates the SAT.

The SAT must be aligned to allow a soldier to accurately hit a target with a conventional rifle sight. Early SATs were bolted to the rifle stock and the gun sight was adjusted to align with the laser beam. The disadvantage of this method is that the gun sight must be re-adjusted when using actual ammunition. To overcome this weakness, currently used SATs incorporate mechanical linkages to change the orientation of the laser.

A conventional small arms alignment fixture (SAAF) used by the U.S. Army to align conventional MILES / SATs is used to determine the location of a laser hit on a target reticle. , Consisting of a complex array with 144 sensors used with 35 printed circuit boards. The problem with using traditional SAAFs is that soldiers aim at an array 25 meters away without using a stable gun mount. In many cases, soldiers fire guns at target points that are not at the desired location. Due to its location 25 meters away from the soldiers, the array is affected by snow, fog and wind and has limited visibility in low light conditions in the early morning and dusk.

Conventional SAAF calculates the number of error "clicks" in both the left and right and height (up and down). The number of error clicks is four sets of electro-mechanical indicators (electro-mec
traditional SAAF using hanical display indicators)
Will be displayed. The soldier must turn the conventional SAT adjuster in the correct direction by the corresponding number of clicks. Then you must aim again and fire the gun, and make the corresponding additional adjustments. This iterative process is a traditional SAFF
Until a zero indication is obtained. This process is very time consuming and tedious due to the usual aiming errors that occur each time a soldier performs aiming of the target reticle. It is not uncommon for a firearm to take about 15 minutes to align, even if it does its best, and alignment adjustments often cannot be achieved accurately.

Alignment processes using conventional SAAF not only take a long time, but also use a large amount of blanks, which increases costs. Conventional SAT lasers are not fired unless a blank fire is ignited or without the use of a special dry fire trigger cable. Conventional SAAFs have a telescope (optical si
ghts), different types of firearms, and no night-vision. Conventional SAAF also cannot accurately determine the energy and encoating of the received laser beam.

Therefore, a small arms SAT that does not use a large target array
It is desired to provide an improved alignment system used for the above. It is also desirable to have an automatic SAT for faster and more accurate alignment. In addition, the laser output of the improved SAT preferably has a different output and a different coding to distinguish between different firearms hitting the clothing portion of the MILES system, respectively.

DISCLOSURE OF THE INVENTION Accordingly, it is a primary object of the present invention to provide an improved firearm laser transmitter for use in a multi-integrated laser engagement system.

The present invention provides a laser transmitter that can be mounted on a firearm. The laser transmitter is capable of supplying energy and generally has a laser that emits a laser beam along the sight of a firearm.
The alignment head of the electro-mechanical alignment system is connectable to the laser transmitter and directs the laser beam up and down until the laser beam is substantially aligned with the aim of the firearm. Adjust the laser transmitter in order to.

The control unit includes a box 22 having an LCD display 24 (FIG. 2). The box 22 also has a keypad in the form of a membrane switch panel. This switch panel surrounds the display 24 and includes push-type switches 26, 28, 30, 32, 34, 36 and 38.
Contains.

The shrinkable slide rack 40 can extend horizontally from the rear end of the base unit 42 (FIG. 1B) mounted on the bottom wall of the container 16. The barrel 44 of the rifle 14
The base is fixedly supported on the top of a triangular gun mount 46 fixed to the middle of the base unit 42 with bolts. The trigger guard (not shown) of the rifle 14 is mounted in a vise 48 of the rack 40. The vise 48 has manual adjustment knobs 50 and 52 for the barrel 44 of the rifle gun 14 in the vertical and horizontal directions, respectively. Rifle gun 14 with gun rack 46
After being mounted on the vise 48, the soldier 21 (FIG. 1A) sets a standard on the target reticle image 54 (FIG. 6) projected onto the aiming line of the firearm. The details will be described later.

Box-shaped optical unit 56 (Figs. 1A and 1B) is the base unit
42 (FIG. 1B). Optical unit 56
Includes a concave lens 58 (FIG. 6) and a beam splitter 60. The beam splitter 60 is an infrared light from a laser transmitter (SAT) 12 (FIG. 1).
t) is transparent, but reflects visible light. The target reticle 54 (FIG. 6) is mounted inside the optical unit 56 below the laser beam axis. Beam splitter 60
Is disposed in front of the concave lens 58 and is inclined by 45 degrees, and projects a V-shaped image of the target reticle through the lens 58 at infinity. The position sensor detector 62 in the optical unit 56 receives the laser beam L2 and generates an error signal indicating a deviation between the position where the laser beam is received and the target reticle image. After that, the SAT12 detects the laser beam L2
Adjusted until the center of 2 is illuminated.

The control circuit in the control unit 20 (FIG. 1) is connected to an alignment head 64, which is mechanically coupled to the rear end of a laser transmitter (SAT) 12 bolted to the rifle 14. I have. This control circuit causes the alignment head 64 to repeatedly fire a laser within the laser transmitter 12.
Utilizing the error signal, the control circuit causes the alignment head to independently rotate a pair of wedge prisms 66 and 68 (FIG. 3), each including a spur gear, in the SAT 12 so that the laser beam is turned on the barrel 44 of the firearm. The laser beam is adjusted up and down (high and low) to the left and right until it is substantially aligned with the sight.

The alignment system 10 can be used for automatic aiming alignment of all U.S. Army designated small arms and machine guns,
It is possible to fully cope with new firearms. The automatic operation of this system is quick (within one minute) accurate with a single initial aiming of firearm 14 by soldier 21,
Provides reliable SAT12 aiming reliably. With the use of the sight vise 48, the telescopic sight mounted on the firearm 14 and the night-vision device do not interfere with aiming. Since the entire alignment system 10 continues within the closed-room transit case 16, the case 16 also functions as a shield for sunlight and bad weather. Alignment system
10 does not use empty packages during alignment. Therefore, it can be used anywhere such as indoors or on a table.

Initial setting of the alignment system 10 requires three steps. That is, the step of installing the battery in the control unit container 22 (FIG. 1) and the operation of the BIT switch 30
An operation step (FIG. 2) and a step of selecting a firearm type to be aligned by pressing the switch 34 are shown. display
24 provides the operator with appropriate text messages and instructions to proceed to the next step. When the alignment system 10 is ready for alignment work, the soldier 21 aligns the firearms according to the instructions on the display 24. Typical steps are as follows.

a) Attach the alignment head 64 to the laser transmitter (SAT) 12.

b) Place the firearm in the sight vise 48 and the gun mount 46 in front.

c) Aim the firearm at the illuminated target reticle image 54 visible in the optical unit using the vertical and horizontal adjustment knobs 50 and 52 of the sight vise.

d) Press the progress switch 28 (FIG. 2) and follow the instructions on display 24. The firearm type is selected by pressing switch 34 in response to the displayed question.

e) Press the align switch 26 of the control unit container 22 when the firearm is ready to fire.

f) Display 24 “Alignment completed (AL
IGNMENT COMPLETE) ”message.

g) Remove the firearm from the alignment system according to the instruction to complete the alignment.

If problems occur with the alignment system 10 during the alignment process, such as low power, incorrect laser coating, or trigger issues, the alignment system indicates that the soldier has a broken SAT on the firearm and needs to be replaced Let them know.

The overall operation of alignment system 10 is shown in block diagram form in FIG. Firearm 14 is mounted on sight vise 48 along with alignment head 64 mounted on SAT 12. The optical unit 56 is an illuminated target reticle 54
To which the sight of the firearm is aimed. When the align switch 26 (FIG. 2) is actuated, the control unit 20 repeatedly activates the SAT 12 while simultaneously reflecting the SAT reflective LED mounted behind the window 70 (FIG. 3) display.
Monitor the proper operation status (not shown). The optical unit 56 senses the position of the laser and sends the data to the control unit 20 to determine the required correction amount.
After that, the control unit 20 sets the alignment head 64 to SAT1.
Make the necessary adjustments to 2. This process continues in real time until the SAT 12 is correctly aligned.
The control unit 20 also monitors the laser power level and laser code along with the optical unit 56, and also checks whether the alignment optical functions of the SAT are performing as desired. Details of the five main subassemblies of the alignment system 10 will be described later.

The optical unit 56 (FIG. 1B) is an assembly that projects the illuminated target reticle 54 against the soldier during the aiming operation and senses the position of the firearm laser beam relative to the target reticle. The illuminated target reticle 54 helps the soldier to aim in dark conditions, such as at dawn or at sunset. FIG. 6 shows the role of the main components of the optical unit 56. One large convex lens 58 performs collimation of the laser beam and focuses the laser beam on the position sensor detector 62 located at the focal point of the lens 58. When the angle of incidence of the laser beam on the lens 58 is not vertical (misalignment), the position of the spot on the detector 62 is in an offset state. The detector 62 passively quantifies the offset amount and sends the error to the control unit 20. The detector is preferably a quad-de-detector.
a solid state device such as a tector, or a linear detector with an analog output. A beam splitter 60 is present in the laser beam path. It reflects visible light and transmits infrared light from the laser. The beam splitter 60 is held at an angle of 45 degrees and projects the target reticle image 54 through the same lens as the input laser. The aiming target reticle 54 is illuminated with visible light, such as an LED 72, and adjusted so that the projected image is located on the same optical axis as the zero point of the position sensor detector 62. Optical unit 56
No on-site adjustments are required and the alignment system 10
Does not require electronic equipment other than the detector 62 and the LED light source for illumination of the target reticle 54.

The L-shaped protective barrier 74 (FIG. 1) is firmly bolted to the base unit 42 between the tip of the barrel 44 of the firearm and the optical unit 56. This barrier prevents a soldier from inadvertently touching the lens 58 of the optical unit with the barrel 44 when mounting the rifle 14 on the gun rack 46 and the vise 48. The barrier has a through hole covered by a metal screen 76 to pass a laser beam, which may be on the order of 8 mm wide, to the optical unit 56. A glass cover or other transparent cover would not be desirable for this through hole. This is because they may become dirty, weaken or refract the laser beam, and cause a problem in accuracy.
