| Abstract: | 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. |
