Title:
METHOD FOR FAST SWITCHING LIQUID CRYSTAL ON SILICON SPATIAL LIGHT MODULATOR
Document Type and Number:
WIPO Patent Application WO/2021/022505
Kind Code:
A1
Abstract:
A method for fast switching liquid crystal on silicon (LCOS) spatial light modulator, is fast variation of the phase modulation by an LCOS device as a function of driving voltage. The time of the variation of the phase modulation of an LCOS device can be reduced by increasing and adjusting driving voltage. The driving voltages are set as VB ('B' denotes black) and VW ('W' denotes white frame). The time of an LCOS device can be reduced by increasing driving voltage VB from 0.8V to a higher available value 2.2V. Driving voltage VW is set accordingly, to keep the phase depth φ 0 equal π radians for amplitude modulation, or equal 2 π radians for phase modulation in a range from 2.5 to 5.0V.
