Abstract
A directional photodetector comprises a photosensitive element and a light selector. The photosensitive element comprises a single-photon avalanche diode, SPAD, or an array of SPADs or SPAD array. The light selector is arranged on or above the photosensitive element, in particular on or above an active surface of the photosensitive element. The light selector is configured to restrict a field of view of the photosensitive element at least for light with a wavelength within a specified wavelength range. The light selector is configured to restrict the field of view by predominantly passing light with a direction of incidence within a range of passing directions of the light selector.
