Characterization of photochromic computer-generated holograms for optical testing

摘要

We investigate the possibility to produce photochromic CGHs with maskless lithography methods. For thispurpose, optical properties and requirements of photochromic materials will be shown. A diarylethene-basedpolyurethane is developed and characterized. The resolution limit and the inuence of the writing parameterson the produced patterns, namely speed rate and light power, have been determined. After the optimization ofthe writing process, gratings and Fresnel Zone Plates are produced on the photochromic layer and diractioneciencies are measured. Improvements and perspectives will be discussed.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE). Downloading of the abstract is permitted for personal use only.
