Abstract
There are optical devices compatible with computers, which make it possible to decode the fringe patterns obtained by various optical techniques such as: holographic interferometry, the method of photoelasticity, the moire method, etc. in the semi-automatic regime. As it often happens in Russia such expensive equipment is not available at research and educational institutions but they possess quite a large number of computers and standard peripheral devices for them. Referring to the above mentioned the authors have developed a technique of fringe patterns decoding bases on the use of standard hardware and on the integrated system of automation of mathematical and engineering calculations MathCad 2.01. Applying the given technique the authors used the following devices: IBM PC AT 386SX CPU 33.3 MHz, ScanJet HP (Hewlett Packard Corp.). The errors of this technique have been investigated as well as the range of its application. The technique is illustrated by the examples of decoding of holographic interferograms, moire and photoelastic patterns.
