摘要
实验通过改变起偏器、检偏器的夹角和LCD两端电压,得到液晶光阀的电光效应曲线,并利用液晶光阀制作实时计算全息图。由实验结果可得出:1)外加电压较弱时,线偏振光经过LCLV(liquid crystal light valve)后发生偏转,曲线无变化;2)外加电压达到一定值时,垂直入射的线偏振光不发生偏转,电光效应曲线有显著变化;3)U≥U0时,光透过率发生突变,呈近似直线的非线性变化,最终达到最大值。
Electro-optical curve of LCLV was obtained by changing the included angle between polarizer and analyzer;the voltage values of LCD and the real-time computer-generated hologram were manufactured.The result shows ：1）when the voltage is weak,line polarized light will deflect after the LCLV（liquid crystal light valve）,the curve will not change;2） when the voltage reaches a certain value,The line perpendicular incident will not happen to deflect,and the curve has a apparent change;3）Light through rate has a mutation that is a approximate linear nonlinear changes,and finally reaches maximum when U achieves U0.
