Multifunctional optical sensor with a photodetector matrix coupled to a microlens matrix

摘要

A multifunction optical sensor comprising a matrix of CCD or CMOS type photodetectors having a sensing region divided into sub-regions. The optical sensor includes a matrix of microlenses. Each of them is set to focus on light coming from a portion of solid angle 16 above the associated photodetector 12 or cluster of consecutive photodetectors. Each function consists of a single microlens, a single subgroup of microlenses that are contiguous to each other, a composite noncontiguous microlens, and a non-contiguous subgroup of microlenses Tied to The angular distance between the central directions of the portions of the solid angle 16 delimited by adjacent photodetectors or adjacent clusters of photodetectors is not constant within the matrix.
