Measurement of diameters of electrical wires using laser with microprocessor

Abstract

A simple technique is described to measure the diameters of thin electrical wires using laser with microprocessor. A wire is moved across the laser beam. This results in change in the photodetector output for a finite time duration which is determined using a microprocessor. The product of the time duration and the velocity with which the wire is moved gives the diameter of the wire. This technique can be used to measure the size of the large objects. This technique is also a noncontact method and can be used in hostile environments.
