Abstract
A multispectral sensor comprises an opaque housing having a first chamber with a first aperture and a separate second chamber with a second aperture. An optical emitter is arranged in the first chamber and is arranged to emit light of a specified wavelength or range of wavelengths through the first aperture. An optical sensor is arranged in the second chamber and arranged to detect received photons through the second aperture. A control unit is configured to initiate emission of light by the optical emitter and a measurement unit is configured to provide sensor signals generated by the optical sensor. The optical sensor comprises an array of sensor pixels of a first type and pixels of a second type. The pixels of the first type each have a different transmission characteristic, each generating a multispectral sensor signal, respectively. The pixels of the second type have a same transmission characteristic and each generate a compensation sensor signal.
