Programmable CGH on photochromic plates coded with DMD generated masks

Autor: R, Alata, G, Pariani, F, Zamkotsian, P, Lanzoni, A, Bianco, C, Bertarelli

Publikováno v: Optics express. 25(6)

Computer Generated Holograms (CGHs) are used for wavefront shaping and complex optics testing. Present technology allows for recording binary CGHs. We propose a Digital Micro-mirror Device (DMD) as a reconfigurable mask, to record rewritable binary a
