FIELD: radio engineering. SUBSTANCE: device includes forming optical system, matrix photodetector and electron signal processing unit. Optical disc placed between forming optical system and matrix photodetector in focal plane of forming optical system is inserted to record information on spatial position of pulse source of optical radiation. Optical disc is put on shaft of stepping motor and is fabricated in the form of thin metal layer deposited on transparent dielectric which provides for capability to take bearings on pulse sources of optical radiation having high power density, for instance, laser ones. Besides that disc is insensitive to actions of external fields of electromagnetic and ionizing radiations which makes it possible to determine angular coordinates of pulse sources of optical radiation against background of external noises. For information reading optical disc is illuminated with additional source. Synchronization of moment of light flash from additional illumination source with moment of adjustment of element of surface of optical disc with recorded information uniaxially to center of window of matrix photodetector is ensured thanks to insertion of delay line. EFFECT: enhanced precision and reliability of device. |
