Abstract
A sensor stack is described. The sensor stack includes first and second electromagnetic radiation sensors. The first electromagnetic radiation sensor has a high quantum efficiency for converting a first range of electromagnetic radiation wavelengths into a first set of electrical signals. The second electromagnetic radiation sensor is positioned in a field of view of the first electromagnetic radiation sensor and has a high quantum efficiency for converting a second range of electromagnetic radiation wavelengths into a second set of electrical signals and a low quantum efficiency for converting the first range of electromagnetic radiation wavelengths into the second set of electrical signals. The first range of wavelengths does not overlap the second range of wavelengths, and the second electromagnetic radiation sensor is at least partially transmissive to the first range of electromagnetic radiation wavelengths.
