Method for producing a beam shaping holographic optical element
摘要:
A method for recording a plurality of scatter volume holograms in a photopolymeric recording medium, the method including at least the following steps providing a first laser light source, providing a photopolymeric recording medium including a substrate and a photoactive layer, wherein the photopolymeric recording medium has an index modulation Δn of at least 0.04 and a thickness d of the photoactive layer of at least 25 μm, and irradiating the photopolymeric recording medium with the first laser light beam generated by the first laser light source with a minimum irradiation energy dosage of 3*Di, Di being the inhibition dosage of the photoactive layer.
