Multifunctional optical sensor comprising a matrix of photodetectors coupled microlenses |
摘要 |
<p>Multifunctional optical sensor, comprising a matrix of photodetectors (12) of the CCD or CMOS type, having a sensitive area divided into sub-areas, each of which, individually or combined with others, is dedicated to a specific function of monitoring the scene or measuring environmental parameters. The optical sensor comprises a matrix of microlenses (14), each of which is set to focus the radiation coming from a portion of solid angle (16) on the associated photodetector (12) or cluster of mutually contiguous photodetectors (12). Each function is associated to a single microlens or to a single subgroup of mutually contiguous microlenses or to multiple, not mutually contiguous microlenses or to multiple, not mutually contiguous subgroups of microlenses. The angular separation between the central directions of the portions of solid angle (16) subtended by adjacent photodetectors or adjacent clusters of photodetectors is not constant within the matrix.</p> |
