DEVICE FOR LOCATION OF SPACE WITH DOUBLE SENSITIVITY ZONE Russian patent published in 2020 - IPC G01S17/02 

FIELD: physics.

SUBSTANCE: invention relates to optical location of space and can be used in systems for preventing collision of vehicles, as well as in aircrafts for detecting high-speed objects. Disclosed device for locating space with dual sensitivity zone comprises an optoelectronic unit, light sources in a transmitting optical system with a radiation field, receiving optical system – a lens with a field of vision, a mirror placed before the transmitting optical system and the lens, wherein the sensitivity zone is formed by crossing the radiation field of the transmitting optical system and the field of view of the receiving optical system. Mirror is made of two parts, one of which is cone, the other truncated cone, wherein cones are located on central axis of device, with possibility of changing distance between them. Lens is provided with a filtration coating, and the sensitivity zone is composed of two conical zones, each of which is represented by one mirror and n light sources tuned to a given wavelength.

EFFECT: creation of a double conic sensitivity zone, increase in the number of light sources served by one photodetector, possibility of operation of the device in two ranges.
