The quantitative analysis of a two-medium mixture using holographic interferometry: the determination of the size corresponding to circular- and rectangular-column voids in a two-medium mixture

The purpose of this paper is to extend the holographic technique to the opt ical measurement of a two-medium mixture. Assume there exists a void in med ium A and the void contains medium B, an experimental technique and the cor responding theories are proposed in this paper, in order to quantitatively determine the size of void in the two-medium mixture. Then the amount of me dium B can be determined. An empty glass container was simulated as a void in the mixture. Two different types of glass containers were used and the c orresponding theories were derived. The test results show that the errors w ere in a reasonable range and support the application of holography in the quantitative optical measurement of a two-medium mixture.
