Easy ways for performing real-time holographic interferometry education
Author(s): Ming-Wen Chang

Paper Abstract

Holographic interferometry experiments are very important in holography education. They are mainly divided into double-exposure, real-time and time average holographic interferometries. Because special equipments such as liquid gate and micropositioning base are very expensive, real-time holographic interferometry experiments which are thought to need those equipments are less popular in general laboratories. There are two well known ways to make real-time holographic interferometry experiments. One way is to replace developed film plate to its original place and another way is to develop film plate in-place. These two ways need the above mentioned very expensive equipments. We show some easy ways and use some simple equipments for film plate in-place developing to make the real-time holographic interferometry experiments possible in general laboratories. Comparisons and analyses of different ways are made. Also the diffraction efficiencies for different conditions are measured. We have the conclusion that movable tank processing in-place film plate developing is recommended.
