Paper Abstract

Meadowlark Optics has developed a variety of spatial light modulators (SLMs) for nondisplay applications. They operate by electrical control of the birefringence of nematic liquid crystals to achieve spatial and temporal modulation of phase and amplitude of light. They modulate phase by electrically varying the effective extraordinary index, n, of a uniaxial layer of nematic liquid crystal. This varies the optical thickness of the layer for light that is linearly polarized parallel to the optic axis of the layer. The SLM's can modulate amplitude for light that is linearly polarized at 45° to this direction if they are followed by an orthogonal or parallel linear polarizer.
