Abstract: The photoresist is used as recording materials to take the master of embossing hologram.This paper gives some illustration about embossing holograms and points out how to take good photoresist master including the choice of taking parameters with high diffraction efficiency and signal to noise ratio, the well distribution of illumination light, the reconstruction of inverse conjugate light, eliminating polarization, coherent length and the influence of external vibration.This paper also presents the higher power laser with good coherence is the key to gain good quality hologram.This paper is written by a lot of experiments and inspecting.
