1. A light detection device, comprising: a first array of pixels formed from at least one layer of semiconductor material having a bandgap corresponding to a first range of wavelengths, the first array of pixels disposed along a focal plane, each pixel of the first array of pixels configured to output one or more first signals in proportion to a position of photons incident thereon that are within the first range of wavelengths, the one or more first signals referenced to a ground common; a second array of pixels formed from at least one layer of semiconductor material having a bandgap corresponding to a second range of wavelengths different from the first range of wavelengths, the second array of pixels disposed along the focal plane, each pixel of the second array of pixels configured to. generate one or more second signals in proportion to a number of photons incident thereon that are within the second range of wavelengths, the one or more second signals referenced to the ground common; wherein the second array of pixels are disposed outwardly from the first array of pixels along an optical path of both the first and second array of pixels, the first and second arrays of pixels arranged along respective planes that are parallel to each other and to the focal plane and that are perpendicular to the optical path, such that photons travel along the optical path from the first array of pixels to the second array of pixels.
