Abstract

The laser thickness gauge discribed in this paper can be used to measure thickness of plate, band, or film made of steel, iron, rubber, paper, plastics and any non-transparent meterial at real time, on-line and non-contract. It is able to operate in most adverse industry circumstance, such as hot or cold steel rolling production line, and possesses high long-time stability, reliability. It also can be used to measure place, distance or surface shape of any body in like manner. The equipment consists of several parts, such as, laser projectors, optical receivers, electronic signal handling units, computer system, state control system, mechanical gearing and protective system for industry circumstance. We will discribe its main technical distingushing features in this short paper.
