متن کاملA Polarization-Independent Liquid Crystal Spatial Light Modulator
We report our recent experimental results on a new polarization-independent, liquid crystal (LC) spatial light modulator (SLM). Based on a periodic nematic director profile, the modulator acts as a switchable diffraction grating with only 0and ±1st-orders at efficiencies of ≥ 99%, manifests contrast ratios ∼600:1 (for laser light), switching times of ∼ 2ms, and threshold voltages of < 1V/μm. Re...
متن کاملA liquid crystal spatial light phase modulator and its applications [5642-10]
We have developed optically-addressed and electrically-addressed liquid crystal spatial phase-only light modulators without pixelized structures. We obtained a large depth of phase-only modulation based on the electro-optical characteristics of a parallel-aligned nematic liquid crystal. We also confirmed that the satisfactory phase modulation capability and high diffraction efficiency of these ...
متن کاملA Low-Voltage and Fast-Response Infrared Spatial Light Modulator
We report a low-voltage and fast-response polymer network liquid crystal (PNLC) infrared phase modulator. By optimizing the UV curing temperature and LC host, we achieved V2= 22.8V at =1.55m and response time about 1ms. Such a PNLC-based spatial light modulator is useful for adaptive optics, adaptive lens, and laser beam steering. Author
متن کاملOptimized Iterative Method for Phase Retrieval Using a Liquid Crystal Spatial Light Modulator
Recovering the phase information of a diffracted beam has a major interest in several fields such as microscopy, materials research and astronomy. Generally, the solutions fall into two broad categories: interferometric methods and iterative methods based on beam propagation. The latter are known to have easier experimental implementations; they are also less sensitive and are considered as “in...
