MULTIELEMENT PHOTODETECTOR Russian patent published in 2010 - IPC H01L31/42 G01J1/02 

FIELD: physics.

SUBSTANCE: singly connected or multiply connected diaphragm 3 in the cold screen of a multielement photodetector does not fall outside the limits of the section of an area which is common for overlapping figures which are sections of oblique pyramids. Bases of the pyramids coincide with the exit pupil of the objective lens 4, which forms an image on a matrix of photosensitive elements 1. Vertices of the pyramids are in corners of the photosensitive field of matrix 1. The sectional plane of the pyramid coincides with the plane of the diaphragm 3. The design of the photodetector according to the invention prevents stray radiation falling on the matrix of photosensitive elements.

EFFECT: improved parametres of the photodetector.
