Get PDFWe propose a two step method which enables us to obtain transmission Holographic Optical Elements of high diffraction efficiency as well as a good signal-to-noise relation. By means of a device using partially coherent light, a master Holographic Optical Element can be copied in a second photosensitive material. The results which are obtained in dichromated gelatin and photoresist are comparable to those which are obtained directly
