description An optical sensor includes pixels, with each pixel formed by a photodetector and a telecentric system topping the photodetector. Each telecentric system includes: an opaque layer with openings facing the photodetector and a microlens facing each opening and arranged between the opaque layer and the photodetector. Each pixel further includes an optical filter between the microlenses and the photodetector. The optical filter may, for example, be an interference filter, a diffraction grating-based filter or a metasurface-based filter.
