Infrared laser radiation's incidence detecting and determining assembly for e.g. terrestrial vehicle, has group of detection quadrants associated to group of spatial detectors that have same field of vision of quadrants to detect radiations

摘要

The assembly has a group (3) of four circular detection quadrants (5-8) with a large surface, associated to an entrance pupil, where the assembly is arranged for detecting radiations in a spectral band extending from 1 to 12 micrometer, of wavelength. The group of detection quadrants for detecting weak radiations is associated to another group (4) of filiform spatial detectors (10-13) with small surface, where the detectors have same field of vision of the detectors (3) for detecting the strong radiations. The detectors are sandwiched between the detection quadrants. The detectors are sandwiched between the detection quadrants.
