Abstract

The Laser Non-Contact Gauging System (LNCGS) is an instrument designed for fast and accurate non-contact measurement using Laser beam as a probe. In this system, the Laser beam is made to ‘scan’ a particular region at a high speed [1,2]. The scanning beam is focussed onto a photodiode by a collecting lens. When the scanning beam is interrupted by an object, the photodiode senses the shadow, and generates a pulse whose width is proportional to the linear dimension of the object which is intercepted by the plane of scanning beam. This may be measured and processed by suitable electronic circuits to estimate the dimension.
