An optical sensor system adapted to operate through a window of a vehicle includes a lens, a plurality of optoelectronic devices, and an optical device. The lens is configured to direct light from a field-of-view toward a focal plane. The plurality of optoelectronic devices are arranged proximate to the focal plane. The plurality of optoelectronic devices includes a first optoelectronic device operable to detect an image from a first portion of the field-of-view, and a second optoelectronic device operable to detect light from a second portion of the field-of-view distinct from the first portion. The optical device is configured to direct light from outside the field-of-view toward the second portion.
