Spatial light modulators are based on liquid crystal microdisplay technology (digital
addressing), using Twisted Nematic Liquid Crystalline Materials, and utilizing the
birefringence effect of twisted nematic liquid crystals ,which enables the precision
modulation of the amplitude, phase and power of the incident beam.
This ability of the precision control to the phase of the wavefront makes spatial light
modulators become ideal choice for applications such as beam shaping and phase
correction, educational research, biomedical imaging, and digital holographic experiments.
