Abstract: The invention relates to an image sensor comprising: •an optical system (2a) for receiving an optical signal; •a Bayer matrix (4) located on the image focal plane of the optical system (2a), the Bayer matrix (1) comprising: a reference optical filter (B1) configured to eliminate or attenuate, in the received optical signal, a first band of wavelengths and to allow through, in the received optical signal, a second band length of wavelengths, and also eight optical filters adjacent to the reference optical filter (B1); •a phase mask (2c, 22, 28) arranged on a pupil (2b) of the optical system (2a) and configured to selectively project at least 98% of the energy of the optical signal carried in the first band of wavelengths and 98% of the energy of the optical signal carried in the second band of wavelengths on the reference optical filter (B1) and on at least one adjacent optical filter, which is configured to allow through, in the received optical signal, the first band of wavelengths.

Abstract: A detection and locating device comprising a plurality of optical sensors (Q1, Q2, Q3, Q4) having fields that together define the field of the detection and locating device, each sensor having a plurality of photodiodes having fields that together define the field of the sensor, the sensors being connected to a control unit (10) in such a manner that each sensor supplies a first signal corresponding to the sum of the signals from at least two of the photodiodes.

Abstract: The invention relates to an optronic system for identifying an object including a photosensitive sensor, communication means and a computerized processing means making it possible to reconstruct the object in three dimensions on the basis of the images captured by the sensor and to identify the object on the basis of the reconstruction. The photosensitive sensor is able to record images of the object representing the intensity levels of an electromagnetic radiation reflected by the surface of the object captured from several observation angles around the object and the communication means are able to transmit the said images to the computerized processing means to reconstruct the object in three dimensions by means of a tomography function configured to process the images of the object representing the intensity levels of an electromagnetic radiation reflected by the surface of the object.
