Amorphous silicon based multi-level holograms (Conference Presentation)
The original image has been processed by sampling, calculating and encoding to achieve a-Si based hologram patterns using MATLAB. Through the investigation of the relationship between laser fluences and phase modulations (π), the calculated hologram pattern has been fabricated with femtosecond laser processing. The holographic image is captured using CCD by illuminating the hologram patterns with 561 nm laser beam. The conversion efficiency of 0.82% has been measured using an optical meter.
