<p>The present invention relates to an apparatus for blocking a laser beam in an optical system for a target, and more specifically, relates to an apparatus for blocking a laser beam in an optical system for a target which detects and traces the target in an aircraft and acquires distance information. An embodiment of the present invention comprises: a laser transmitter for oscillating polarized light of a laser with a substance of a polarized wave; an object lens for penetrating and radiating the polarized light of the laser and receiving light; a camera detector for detecting visible light or infrared light received through the object lens; a mirror for reflecting the polarized light of the laser oscillated by the laser transmitter, providing the polarized light of the laser to the object lens, and reflecting and penetrating the returning polarized light of the laser which fails to penetrate the object lens and returns from among the polarized light of the laser; and a blocking unit for blocking the returning polarized light of the laser which penetrates the mirror to prevent the returning polarized light of the laser which penetrates the mirror from being received by the camera detector.</p> |
