Liquid crystal achromatic polarized switch
摘要
Abstract
In order to realize the controllability of orthogonal change of polarization direction of the po-larized light in the whole visible wavelength range,we research the achromatic polarized light switch composed of liquid crystal wave-plates.The polarization rotation and response characteristics of a liquid crystal wave-plate are analyzed synthetically,and compared with the polarizing effect of the tra-ditional wave-plate.Then,the achromatic polarized light switch is designed by referring to the design of the combined achromatic wave-plates.Two polarized light switches with two different structures are simulated by Tech Wiz LCD 1D software,and its polarization rotation effect and response charac-teristics were obtained.The contrast ratio of different wavelength polarized light was calculated.The simulation results show that the liquid crystal achromatic polarized light switches showed in this paper can realize the orthogonal change of the polarized direction of polarized light in the wide visible wave-length,and the polarized light has a high degree of polarization.Under the 20 V driving voltage,the turn on time is 0.3 ms and the turn off time is 4.5 ms for the polarization rotation switch.The results are fit for the requirements for achromatic polarized light switch.关键词
