First Claim
Patent Images
1. An optical system comprising:
- at least one illuminator that illuminates a profile of a vehicle operator; and
an imager in direct optical communication with a reflector, wherein the imager captures a directly reflected image of the vehicle operator profile from the reflector, and the reflector is adhered to a portion of an inboard surface of a vehical windshield in optical communication with the vehicle operator and comprises a reflective layer and a substrate layer, wherein the reflector does not include a metal layer.

21. A method for illuminating and capturing images of a vehicle operator'"'"'s profile comprising the steps of:
-
positioning at least one illuminator within a passenger compartment of a vehicle; positioning a reflector on a portion of an inboard side of a windshield in optical communication with a vehicle operator, wherein the reflector comprises a first layer of quartz material and a second layer consisting of a multi-layer dielectric material, wherein the reflector does not include material; positioning an imager within the passenger compartment about a valance panel of the vehicle such that the at least one illuminator, reflector, and imager are all in optical communication and the reflector and imager are in direct optical communication; and regulating a captured directly reflected image of the vehicle operator profile by positioning the imager at a horizontal distance from the windshield. - View Dependent Claims (22)
