An optical device that electrically regulates the spatial distribution of light amplitude, phase, or polarization is called a spatial light modulator (SLM). It is extensively employed in cutting-edge fields like optical communication, laser beam shaping, and holography.
A liquid crystal on silicon (LCOS) micro-display and micro-projection technology is used for LC projectors and rear-projection televisions. LCOS is typically a reflective type LC panel made up of LC on a Si substrate and a reflective layer.
Using semiconductor manufacturing technology, switching components and electric wires for LC driving are integrated on a Si substrate beneath a reflective layer, producing a seamless, high-pixel-resolution image.
Using proprietary LC materials, Santec has created a novel LCOS device for a range of uses, including fiber optics.
