Abstract

Holographic interferometry is a well established technique for accurate measurements of mechanical displacements. In cases where no prior information is available on the lcoations of zero displacement, there has not been a method which allows one to determine the location of the zeroth order interferometric fringe. We wish to demonstrate that by using three wavelengths to record color interferometric holograms, the zeroth order fringes are easily identified.
