Pixel size and pitch measurements of liquid crystal

Banyal, R. K; Prasad, B. R (Indian Academy of Sciences, 2005-08)

We present a simple technique for the determination of pixel size and pitch of liquid crystal (LC) based spatial light modulator (SLM). The proposed method is based on optical diffraction from pixelated LC panel that has ...
Spatial light modulator for wave-front correction

Vyas, A; Roopashree, M. B; Banyal, R. K; Prasad, B. R (Department of Applied Optics and photonics, University of Calcutta, 2009)

We present a liquid crystal method of correcting the phase of an aberrated wave-front using a spatial light modulator. A simple and efficient lab model has been demonstrated for wave-front correction. The crux of a wave-front ...
