OPTICAL DEVICE FOR THE OBJECTS DETECTION Russian patent published in 2018 - IPC G01S17/02 

FIELD: optics.

SUBSTANCE: invention relates to a location domain. Optical object detection device comprises an optoelectronic unit, light sources in the transmission optical system with a radiation field, an objective with a field of view, a mirror placed before the transmitting optical system and the objective. Sensitivity zone is formed by the intersection of the radiation field of the transmitting optical system and the field of view of the objective. Device is provided with a data analysis unit, a matrix photodetector mounted in the focal plane of the lens, configured to control its field of view, each light source is provided with a collimator, while the data analysis unit, a matrix photodetector, light sources with collimators are mounted in a single optoelectronic unit.

EFFECT: technical result consists in increasing the energy density of radiation per unit area, reducing the number of parts in the composition of the device, increasing the density of the assembly of parts in the device, and increasing the photosensitivity of the device.
