Abstract

The authors present a comparative study between different holographic recording materials used for a simple application involving the recording of a Fresnel lenses. They compare the obtained results with classical holographic recording materials dedicated for this purpose such as DCG and Photoresists. The behaviour of each is compared in terms of sensitivity, diffraction efficiency, noise etc. Moreover, the significant feature in this study, coding scheme is compared as well as duplication techniques (contact-copying and 4-f imaging system)
