29 September 1994 Real-time quantized phase-only filters generation on Epson liquid crystal TV
Author Affiliations +
Epson LCTV has been used as a phase only filter in a correlation set up for pattern recognition. The phase modulation of Epson has been measured using a Mach-Zehnder interferometer. We implement the phase only filter on the liquid crystal using different levels of quantization in the phase. We compare the impulse response and the correlation results obtained with this filter with different levels of quantization. Finally we compare the results with those obtained using high resolution techniques as lithography to produce computer generated holograms.
