Phase calibration of spatial light modulators by means of Fresnel images
Institute of Physics (2009)Reliable application of spatial light modulators (SLMs) as programmable diffractive optical elements requires a thorough calibration. In this paper, we propose a method for calibrating SLMs based on the evaluation of ... -
Poincaré-sphere representation of phase-mostly twisted nematic liquid crystal spatial light modulators
Institute of Physics (2009)We establish necessary conditions in order to design a phase-only wave front modulation system from a liquid crystal display. These conditions determine the dependence of the polarization state of the light emerging from ... -
Use of polar decomposition of Mueller matrices for optimizing the phase response of a liquid-crystal- on-silicon display
Optical Society of America (2008)We provide experimental measurement of the Mueller matrices corresponding to an on-state liquid-crystal-on-silicon display as a function of the addressed voltage. The polar decomposition of the Mueller matrices determines ...
