Abstract
A one-way optical communication system adapted for vehicular use. A light-readable indicia (35) is embedded in a window or mounted on an exterior portion of a moving motor vehicle (10). The indicia (15) is transparent to visible light and is reflective to infrared or ultraviolet light, making it generally invisible to the unaided human eye. A beam (30) of infrared or ultraviolet light located in a fixed position remote from the moving vehicle illuminates the indicia and portions of the beam are reflected from the illuminated indicia in a representative pattern. The reflected beam is detected by a fixed sensor (25), which provides an electrical signal. The signal is analyzed to determine the identity of the motor vehicle.
