We propose an optical system for synthesizing double-phase complex computer-generated holograms using a phase-only spatial light modulator and a phase grating filter. Two separated areas of the phase-only spatial light modulator are optically superposed by 4-f configuration with an optimally designed grating filter to synthesize arbitrary complex optical field distributions. The tolerances rela...
Spatial light modulators are ubiquitous tools for wavefront control and laser beam shaping but have traditionally been used with monochromatic sources due to the inherent wavelength dependence of the calibration process and subsequent phase manipulation. In this work we show that such devices can also be used to shape broadband sources without any wavelength dependence on the output beam's phas...
Dual photoelastic modulator polarimeters can measure light polarization, which is often described as a Stokes vector. By evaluating changes in polarization when light interacts with a sample, the sample Mueller matrix also can be derived, completely describing its interaction with polarized light. The choice of which and how many input Stokes vectors to use for sample investigation is under the...
We carried out real-time optical image subtraction and edge enhancement based on a speckle modulation technique by using ferroelectric liquid-crystal polarization switches and a ferroelectric liquid-crystal spatial light modulator. A ferroelectric liquid-crystal spatial light modulator is employed as a real-time and multiple-exposure optical device, and successful results are obtained from thre...
A Twyman-Green interferometer is used to measure the phase induced by a liquid-crystal spatial light modulator (LC-SLM) via spatial-carrier phase measurement methods in order to characterize the phase response as a function of applied voltage. With the phase response characterized, the LC-SLM can be operated in a closed-loop adaptive optics system. Four separate phase unwrapping algorithms are ...
The combmed use of the photoelectnc and electro-optic properttes of the BI,,SIO~~ (BSO)-crystal leads to a new posslblhty of reahzmg a spa&xl hght modulator Under certam geometrical condrtions, whxh will be discussed, It 1s possible to reahze, that the BSO-crystal becomes blrefrmgent depending on the local fiummance, the physxal connection between the dlstnbutlons of blrefrmgence and lllummance...
