The guided missile laser guidance system using on laser-guided bomb, utilization impinges upon laser light on target object and shows up object is followed the trail of, if object is considered as to astigmatism plate, it is identical with the structure of laser remote control signal receiver in the present invention so, but we know that its object is not in order to increase the photosensitive area of light activated element, but laser light is shown up and followed the trail of, it is a kind of laser guidance system, it not laser remote control system, target can not be the ingredient of guided missile in addition, so also unrelated to the invention.
From foregoing, the device that meets the description in the present invention in reality is too numerous to enumerate, but the purposes of each parts of these devices obviously with the present invention in accordingly the purposes of parts have essential difference.
Because light signal is after scattering, intensity reduces greatly, and in order to make laser pickoff have better susceptibility and anti-interference, laser signal preferably adopts the laser signal of vibration;
Wide from foregoing, laser of the present invention is a branch of thinner light, irrelevant with other characteristic whether with laser, so the laser described in the present invention can be the light that a branch of thinner non-laser light source sends.
Beneficial effect: the laser remote control signal receiver described in the present invention is applicable to light signal and receives, is specially adapted to laser signal and receives; Cost is low, in a lot of situations, compared with photoelectric cell, compares and can reduce up to ten thousand times of even more costs; Area occupied is little, can use certain part of controlled substance as astigmatism plate, does not take any additional areas.
