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 ... -
Spatial-chirp compensation in dynamical holograms reconstructed with ultrafast lasers
American Institute of Physics (2008)A computer generated hologram (CGH) reconstructed with a sub-100-fs laser pulse at the focal plane of a conventional refractive lens experiences a large amount of spatial chirp. We report the shaping of a 12 fs laser pulsed ... -
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 ... -
Use of principal states of polarization of a liquid crystal device to achieve a dynamical modulation of broadband beams
Optical Society of America (2009)A spatially resolved polarization switcher operating over a bandwidth of 200 nm is demonstrated. The system is based on liquid crystal technology and no specific-purpose birefringent element is required. The procedure is ...
