US Patent 10440249 Vehicle vision system camera with semi-reflective and semi-transmissive element

A vision system for a vehicle includes a camera module configured to be disposed at the vehicle so as to have a field of view exterior of the vehicle. The camera module includes a lens, a mirror reflector element, a first imager and a second imager. The mirror reflector element is disposed along a longitudinal axis of the lens and between the lens and the first imager. The second imager is disposed so as to receive light reflected off of the mirror reflector element. The mirror reflector element is partially transmissive to a first type of radiation and is partially reflective to a second type of radiation incident thereon. The first imager is more sensitive than the second imager to the first type of radiation, and the second imager is more sensitive than the first imager to the second type of radiation.
