摘要
本文选取向列相液晶MLC-7700-100制备电控双折射无刻痕液晶光栅,三种液晶光栅的光栅常数分别为200μm,100μm,66.7μm,并采用波长为λ=632.8nm的He-Ne激光为光源,照射液晶光栅。同时对液晶光栅施加频率为f=100Hz的交流信号,在电压驱动下得到不同的衍射光斑,研究电压驱动下第1级衍射光斑的电光特性改变的情况。
In this paper we selects the electrically controlled birefringence liquid crystal grating without scored prepared by nematic liquid crystal MLC-7700-100. Three kinds of constants of liquid crystal grating are 200μm, 100μm, 66.7μm. And use the wavelength h. = 632.8nm by HeNe laser as the light source, illuminate the liquid crystal grating. At the same time, applied ac signal of frequency f = 100Hz on liquid crystal grating. Obtained different diffraction light spots under voltage driven. Research the electro-optical properties change situation of first diffraction spot under voltage driven.
