SINGLE PHOTON DETECTION SYSTEM Russian patent published in 2017 - IPC G01J11/00 G02B6/42 

FIELD: physics.

SUBSTANCE: system includes a module with a reception area, the power guidance, optical module and optical fiber that has a shell with the first and second endings and the core of the first and second ends. The block is on the receiving module. Module includes first, second, third and fourth zones, the reflectivity coefficient of which is different from the surface of the receiving module. The tip of the first end is set in the orientation block, first end core is optically connected to the reception area and the second end of the core is optically connected to the optical radiation source module. The first end of the core has the possibility of optical coupling with the first, second, third and fourth zones.

EFFECT: increasing the efficiency of detection and increasing the reliability of work in conditions of fluctuating external temperatures.
