OPTIC-ELECTRONIC SYSTEM Russian patent published in 2015 - IPC G01S17/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to the field of direction-finding facilities and may be used in systems of detection of small-size targets in the infrared spectral region. The system comprises a receiving lens, analysing optical node with a holder and a non-transparent coating in visible and infrared spectral regions and transparent slots in the form of Archimedes spiral and a radial straight line, a four-element quadrant photodetector, four pairs of a light diode and a photo diode, an actuating holder, mechanically connected via a reducer with a holder and a sensor of angular positions, units of photodetector power supply, four delay lines, a unit of pulse count, a unit of coordinates detection, four units of photo diodes power supply, four units of light diodes power supply. All listed facilities are accordingly arranged and interconnected with each other, at the same time the optical node and the optical node holder are made in a certain manner.

EFFECT: increased accuracy of detection of coordinates and expansion of functional capabilities.
