Abstract
A photodetector device includes: a plurality of light detector elements; and a plurality of filters, in which each filter of the plurality of filters is arranged in front of a light detection surface of a corresponding light detector element to filter incoming light incident on the light detection surface, and in which the plurality of filters are configured to filter at least two different wavelength bands, respectively, of the incoming light, and in which the at least two wavelength bands combine to span a predefined range of wavelengths, and in which each filter of the plurality of filters has a corresponding spectral sensitivity, and in which a sum of the spectral sensitivity curves of the plurality of filters over the predefined range of wavelengths is a constant value.
