DETECTION DEVICE FOR OPTICAL AND OPTOELECTRONIC DEVICES Russian patent published in 2021 - IPC G01S17/06 

FIELD: optoelectronic instrumentation.

SUBSTANCE: invention relates to the field of optoelectronic instrumentation and relates to a device for detecting optical and optoelectronic devices. The device contains a surveillance device, a rangefinder device and a detection device. The detection device contains a transmitting unit with a laser emitter and a telescope and a receiving unit made in the form of a two-channel imaging system with separate registration of s- and p-polarization with the same angular fields. The receiving unit contains a lens, a polarizing divider, a compensator for beams with p-polarization, a polarizer and a photodetector for separate registration of images with s- and p-polarizations. The polarizing divider is made in the form of a prism with a polarizing coating and a plate. The compensator is made in the form of a spherical lens or several lenses. The sensitive area of ​​the photodetector is divided into unequal zones, the interband boundary is shifted by Δ, the boundary of the second channel is shifted by 2Δ where Δ is the area of ​​overlapping images of the two channels at the border of the zones. The focal length of the second channel is reduced while maintaining the angular field.

EFFECT: technical result consists in eliminating the imposition of images at the border between the channels, improving the quality of the images and increasing the accuracy of determining the coordinates of the detected targets.
