Abstract

The basic idea described herein is the concept that the power to operate a scanning system is supplied via a laser beam incident on a photocell surface, which is integral with the scanning head. The scanning head is constrained by the mechanics that move it such that the laser beam always contacts the photocell surface. This photocell is not the data sensor; it is merely the power receptor.

Light Powered Scanning Cell Without Wires

The basic idea described herein is the concept that the power to operate a scanning system is supplied via a laser beam incident on a photocell surface, which is integral with the scanning head. The scanning head is constrained by the mechanics that move it such that the laser beam always contacts the photocell surface. This photocell is not the data sensor; it is merely the power receptor.

Information read by the data sensor is transmitted by radio-frequency techniques to a receiver located in reasonable proximity to the scanning unit, but not physically attached. The digital aspects of the device are that the analog-to- digital conversion electronics may be fabricated along with the data sensor on the same silicon or other semiconductor substrate, and the entire unit receives operating power from the energy in the laser beam.
