GEAR FINDING ANGULAR POSITION OF PULSE SOURCE OF OPTICAL RADIATION Russian patent published in 1997 - IPC

FIELD: radio engineering, determination of angular coordinates of object emitting high-power pulse optical radiation. SUBSTANCE: gear comprises forming optical system, matrix photodetector and electron signal processing unit. Optical disc arranged between forming optical system and matrix photodetector in focal plane of forming optical system is inserted into gear for recording of information on spatial position of pulse source of optical radiation. Optical disc is put on shaft of stepping motor and is manufactured in the form of thin metal layer deposited on transparent dielectric which provides for capability of finding direction to pulse sources of optical radiation with high density of power, for instance, laser ones. Apart from this, disc is insensitive to actions of outer fields of electromagnetic and ionizing radiations which makes it possible to determine angular coordinates of pulse sources of optical radiation against background of outside noises. Additional source is used to illuminate optical disc for information reading. Synchronization of moment of flash of light from illumination source with moment of bringing of element of optical disc surface with recorded information uniaxially to center of matrix photodetector window is provided by insertion of delay line. EFFECT: expanded application field, enhanced functional accuracy of gear. 2 cl, 3 dwg
