High recognition ability infrared sensor and thermal camera with such a sensor

摘要

The invention relates to a high recognition ability infrared sensor for target acquisition and tracking. The infrared sensor according to the invention includes, in the cold plane of a cryostat, a matrix (1) which is responsive within a main spectral band and is organised into k stripes, and a strip (3) which is responsive within an ambiguity-removal spectral band, forming a stripe parallel to the stripes of the matrix. A clock generator (4) controls integration times of the independent charges in each of the stripes and a processing device (6) compares, after compensating the time discrepancies, the various useful signals S1 to Sk, Sb delivered by reading and amplifying means (100). Application to target location in the presence of natural or artificial disturbances engendering a large dynamic in the light energy to be detected. IMAGE
