Integrated optical multiple distance sensor for object position detection in vehicle - has rows or arrays of position sensitive diodes and LEDs or laser diodes, with transmission and reception lenses
Integrated optical multiple distance sensor for object position detection in vehicle - has rows or arrays of position sensitive diodes and LEDs or laser diodes, with transmission and reception lenses
The sensor includes position sensitive diodes (2) arranged in lines or an array, a reception lens (4), transmitting LEDs or laser diodes (1) also arranged either in rows or in an array, and a transmission lens (3). The lenses cover a surface or spatial angle. The distance measurement is performed using the triangulation principle. The position sensitive diodes and the LEDs or laser diodes are arranged in rows or arrays closely adjacent to each other. USE/ADVANTAGE - For use in all types of motor vehicle for detecting obstructions during reversing. Compact.
