Astigmatism plate uses translucent box to be to make light repeat after entering the cavity of box multiple reflections, increasing the light intensity on photosurface.
It not that the strongest place directly can replace box as astigmatism plate with metope at ambient.Because people use the environment of electric light typically will not light very strong, so there is feasibility with metope for astigmatism plate.As long as light-sensitive element is tiltedly towards metope, other structures are identical with the laser remote control signal receiver with fan-shaped flat box as astigmatism plate.
For the consideration more visualizing and readily appreciating, the most still illustrate as a example by the fan-shaped flat box laser remote control signal receiver as astigmatism plate.

It is positioned at the light-sensitive element of left and right, receives the optical signal after being scattered by television screen, produce the corresponding signal of telecommunication, and pass to signal processing apparatus.The signal of telecommunication is sought after the recovery by signal processing apparatus, by analyzing difference and the situation of change of difference, can obtain plane of illumination situation of left and right transverse movement on television screen of laser.
In the case of not carrying out extremely complex remote control, only the signal of telecommunication can be compared formula and ask poor, and not carry out concrete simulation quantitative analysis, thus simply astigmatism plate face is divided into multiple digitized region representing different digital amount.
The motion conditions horizontal and vertical by analyzing plane of illumination, can obtain plane of illumination motion conditions on whole television screen.By analyzing plane of illumination motion conditions on television screen, television set is controlled accordingly.
As, utilize the plane of illumination signal as voicing sound of the laser moved up and down on the left of television screen;Utilize the plane of illumination of the laser moved up and down on the right side of television screen as the signal adjusting platform.In addition the simple combination that can utilize some simple motions carries out the remote control of complexity to television set, it is possible to the mode utilizing action to be combined with button carries out the remote control of complexity to television set.

Astigmatism plate face has been divided into four digitized regions representing different digital amount by said process.
By said method, astigmatism plate 525 (television screen) be divide into four numeric areas.
Single-chip microcomputer, to difference signal, scans ten each second.Under open state, if scanning result is identical with last time, data do not charge to single-chip microcomputer.If scanning result is different from last time, then data charge to single-chip microcomputer, and utilize these data to judge how television set operates.Plane of illumination situation, single-chip data situation, television set controlled actuation correspondence situation are as follows:
Under off-mode, plane of illumination is positioned at astigmatism plate 525 (television screen) upper five second continuously, as long as i.e. single-chip microcomputer has data to read in five seconds continuously, no matter has read in any data, all control signal processing means can turn on television set.
Under open state, plane of illumination moves to lower left from upper left side, and the data that single-chip microcomputer reads in are 0010, controls television set and turns down volume continuously.
Again make plane of illumination move to lower left from upper left side in three seconds, single-chip microcomputer again read in be 0010 data, control television set quickly turn down volume.This operation is performed a plurality of times, can further speed up and turn down volume speed.
Under open state, plane of illumination moves to upper left side from lower left, and the signal that single-chip microcomputer reads in is 1000, controls television set and heightens volume.
Again make plane of illumination move to upper left side from lower left in three seconds, single-chip microcomputer again read in be 1000 data, control television set quickly heighten volume.This operation is performed a plurality of times, can further speed up and heighten volume speed.
Heighten or turn down under volume status, as long as plane of illumination does the motion across left-half and right half part, what i.e. no matter single-chip microcomputer read in is which data in 0001,0100,1011,1110,0011,1100,0110,1001, all the execution of control signal processing means can stop heightening or turning down the operation of volume.
Under open state, plane of illumination moves to lower right from upper right side, and the data that single-chip microcomputer reads in are 0111, controls television set and adjusts platform continuously to the direction of channel label reduction continuously.Adjust platform speed relatively slow, adjust platform frequency to be set to five seconds.
Again make plane of illumination move to lower right from upper right side in three seconds, single-chip microcomputer again read in be 0111 data, control television set accelerate adjust platform.It is performed a plurality of times and changes operation, tune platform speed can be further speeded up.
Under open state, plane of illumination moves to upper right side from lower right, and the data that single-chip microcomputer reads in are 1101, and platform is adjusted in the direction that controlling television set increases to channel label continuously continuously.Adjust platform speed relatively slow, adjust platform frequency to be set to five seconds.
Again make plane of illumination move to upper right side from lower right in three seconds, single-chip microcomputer again read in be 1101 data, control television set accelerate adjust platform.It is performed a plurality of times and changes operation, tune platform speed can be further speeded up.
Adjust under mesa-shaped state, as long as plane of illumination does the motion across left-half and right half part, what i.e. no matter single-chip microcomputer read in is which data in 0001,0100,1011,1110,0011,1100,0110,1001, all control signal processing means can perform to stop the operation of tune platform.
Under open state, making plane of illumination move to lower right from upper left side, the data that single-chip microcomputer reads in have two kinds of possibilities, 000111 and 001011.
Being moved to lower left by upper right side again in two seconds, the data that single-chip microcomputer reads in have two kinds of possibilities, 010010 and 011110.
After two actions, above-mentioned two groups of data can be combined by single-chip microcomputer, and four groups of data altogether may be had to read in single-chip microcomputers, and respectively 000111010010,000111011110,001011010010,001011011110.
Read in any group of of these four groups of data, all control signal processing means and control television set closedown.
Change the order of two actions, first make plane of illumination move to lower left from upper right side, in two seconds, moved to lower right by upper left side again, four groups of data of the equally possible reading of single-chip microcomputer, the any group of of these the four groups of data read in, the most all control signal processing means control television set and close.
