我们提出并演示了一种基于使用级联扭曲向列液晶空间光调制器的双异或逻辑(XOR)运算的偏振编码加密系统。通过琼斯矩阵方法分析加密系统的传输特性,以产生适合光学实现的偏振调制。实验证明,通过选择偏振方向和调制条件,可以实现具有良好图像质量的二值图像加密/解密。分析和实验结果都被提出并讨论。
We propose and demonstrate a polarization-encoded encryption system based on a doubly exclusive OR logic (XOR) operation using cascaded twisted nematic liquid crystal spatial light modulators. The transfer characteristic of the encryption system is analyzed by the Jones matrix method to yield the suitable polarization modulation for optical realization. An experimental demonstration reveals that the binary image encryption/decryption is achieved with fair image quality by selecting the orientation of polarization and the modulation conditions. Both analytical and experimental results are presented and discussed.
