EQUIPMENT FOR SPACE OBSERVATION AT BACKGROUND OF BRIGHT DISTANT LIGHT SOURCE Russian patent published in 2009 - IPC G01S17/06 

FIELD: physics, optics.

SUBSTANCE: equipment for space observation at background of bright distant light source comprises objective with controlled diaphragm and multi-element photodetector, which are installed in body of optical route of image registration, and also device for optical route protection against radiation of bright distant light source. Equipment is provided with external body, on lower foundation of which body of optical route of image registration is fixed. Device of optical route protection installed in cavity of external body consists of light impermeable screen low-sized in respect to objective in the form of disk with diametral through threaded opening and mechanism of light impermeable low-sized screen displacement relative to objective. Besides mechanism for displacement of light impermeable low-sized screen comprises the first and second step electric motors, shaft with thread of the first stepper electric motor interacts with diametral through threaded opening of light impermeable low-sized screen by type of movable joint screw - nut. Parallel to specified shaft, rod is fixed relative to body of the first stepper electric motor for stopping of rotation of light impermeable low-sized screen during its displacement along the shaft. The body itself of the first stepper electric motor is fixed on flat plank arranged with the possibility of rotation on double-coordinate hinge in plane parallel to upper base of external body of apparatus, under action of the second stepper electric motor, body of which and double-coordinate hinge are fixed on upper base of external body. Besides the first and second stepper electric motors are connected to outputs of electronic unit of optical route protection device control, which is connected to signal output of multi-element photodetector unit and control input of objective diaphragm.

EFFECT: creation of low-sized equipment for space observation, based on digital photo- and video-registering equipment.
