Abstract: Multifunctional optical sensor, comprising a matrix of photodetectors 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, each of which is set to focus the radiation coming from a portion of solid angle on the associated photodetector or cluster of mutually contiguous photodetectors. 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 subtended by adjacent photodetectors or adjacent clusters of photodetectors is not constant within the matrix.

Abstract: An optical device to measure the distance between the device itself and an obstacle/object comprising a unit to emit radiation including an aligned series of sources of radiation coupled to a series of arrangements of lenses to guide the radiation emitted by the sources. An optical acquisition unit comprising a matrix of photodetectors has a field of view including the scene in front of the optical device and including the obstacle. The signals leaving the acquisition unit are sent to a control and processing unit for calculation of the distance from the obstacle. The unit for the emission and conformation of the radiation emits a beam having a transverse section of a form elongated along an axis that is progressively rotated for transverse sections of the beam progressively more distant from the emission unit. In this manner, the distance of the obstacle may be calculated on the basis of the angular position of the section of the beam intercepted by the obstacle, as acquired by said acquisition unit.
