摘　　要：研究了基于RGB模式下的液晶光阀成像规律,揭示了色彩信号与液晶光阀旋光度的关系,找到并描绘了加载在液晶光阀上的色彩信号与透过液晶光阀的激光光强的关系曲线。通过实验获得了拟合曲线,推导了光强与绿色光亮度的简易公式。分析了RGB模式中不同色彩通道对于液晶光阀成像的响应特性,并以此为依据提出了一种可行的图像或文字等信息的加密和解密方法。最后用实例展示了研究成果,取得了比较好的成效。The law of LCLV imaging based on RGB mode is studied.The relationship between color signal and the spin luminosity of LCLV is revealed.The relation curve of the color signal loaded on LCLV and the laser intensity through LCLV is found and depicted.The response characteristics of different color channels in RGB mode to LCLV imaging are analyzed.Based on this,a feasible encryption and decryption method of image or text information is proposed.Finally,an example is given to show the research results and achieve good results.
