First, a conventional HUD device will be explained using diagrams. Figure 1 is a configuration diagram showing a conventional HUD device, where +1) is an optical signal generation section, r2) is a collimation optical section, and (3) is a collimation optical section.

and combiner 13) constitute a HUD device. By the way, the optical signal generating section 1) generates a desired display optical signal, and is, for example, a cathode ray tube.

An explanation will be given below using an example of an optical signal generating section using a cathode ray tube.

A good image (including letters, numbers, markers, etc.) drawn on the cathode ray tube is projected to infinity by the collimation optical section (■), is reflected by the combiner (31), and is reflected as a signal light (51 to the eyes of the observer (6). incident.

Therefore, it appears to the observer (6) as a monk projected at infinity. On the other hand, the combiner (31d incident light from the outside world (
41 also has a transmitting function, so when viewed from the observer (6), the image on the cathode ray tube appears to overlap with the outside world as an image at an infinite distance in the direction of the outside world corresponding to that position. Person (6) can simultaneously obtain necessary information while looking at the outside world.

By the way, in order for the displayed image to be visible to the observer (6), the display needs to be brighter than a certain level compared to the brightness of the outside world, but in the case of an aircraft HOD device, when the outside world is very bright sunlight Since the display is required to be performed at the bottom, the brightness of the two displayed images must range from a maximum of several thousand to more than ten thousand foot lamberts. For this reason, the optical signal generator has conventionally used a high-brightness cathode ray tube, which has made the device larger and
The major drawback was low reliability (short life).

Therefore, in this invention, compared to the conventional HUD device that changes the brightness of the two displayed images according to the brightness of the outside world,
In addition to controlling the brightness of the outside world as seen by the observer so as not to increase it more than necessary, it is possible to maximize the reliability (lengthen the lifespan) of the output signal light (5) of the necessary optical signal generator (1). By making it possible to use display elements other than high-brightness cathode ray tubes, which have relatively low brightness but have unique characteristics (for example, shadow mask type color cathode ray tubes or solid-state light emitting elements), it is possible to improve performance or reduce size and weight. That's what I did.
