Reflective Liquid Crystal Displays
, 2001
"... Abstract—In this review paper, a detailed overview of the trans-flective liquid crystal display (LCD) technology is presented. We first introduce the transflector classifications based on their com-position and properties. Then, in reviewing the development his-tory, we investigate the mainstream tr ..."

Fully tunable active polarization imager for contrast enhancement and partial polarimetry
, 2012
"... We present the design and the practical implementation of a polarimetric imaging system based on liquid-crystal modulators that allows generation and analysis of any polarization state on the Poincaré sphere. This system is more versatile than standard Mueller imagers that are based on optimized, bu ..."

Projection architectures with light emitting diodes and reflective liquid crystal light modulators
"... We present an overview of our work on projection system architectures using light emit-ting diodes and liquid crystal on silicon light valves. This covers the overall design chal-lenges of illumination systems with high power light emitting diodes and our work on LED projectors with two and four liq ..."
Liquid-Crystal Adaptive Lenses With Modal Control
- In Optics Letters
, 1998
"... orrection of low-order aberrations such as of defocus and astigmatism is of primary importance. The adaptive lenses described in Refs. 2 -- 4 and references therein are controlled by arrays of individual electrodes, approximating the wave front by step functions by means of the zonal correction prin ..."

principle. Good approximation to a continuous wavefront prof ile in these modulators can be achieved only with a large number of discrete control electrodes. We suggest a novel approach to forming a smooth continuous distribution of the refractive index in a nematic LC layer over the entire aperture of LC
Photoelastic modulation polarimetry and its measurement of Twisted Nematic Liquid crystal
"... For in situ/real time measurement, a retarder is substituted by a photoelastic modulator (PEM) in a polarimetry. The azimuthal position of the strain axis of PEM is directly determined with respect to the orientation of the transmission axis of polarizer and analyzer. The Mueller matrix of a twisted ..."
