Abstract

Holographic interferometer is used with a dye-doped photopolymer on one of its arms, the sample is radiated simultaneously with two wavelengths, and measuring the pattern fringe displacement we can calculate the refraction index changes. The photopolymer we use is a mix of Norland Optical Adhesive No. 65 and Crystal Violet dye deposited between two glass plates making a cell of 220 microns thickness. The sample is radiated with a beam from an Ar-ion laser at 515 nm; in the interferometer we employed a He-Ne laser at 633 nm in emission line. We show some experimental results.
