Abstract
A method of real-time image subtraction is proposed that uses successive light transmission through two similar liquid-crystal television (LCTV) panels. The polarization modulation properties of light transmitting through LCTV's are investigated theoretically and experimentally for the case of when the video signals are applied to the LCTV's. Image subtraction is accomplished by the approximate rotations of the linear polarization of light through the LCTV's.
摘要
提出了一种实时图像减法方法，该方法利用光连续透过两个相似的液晶电视（LCTV）面板。针对视频信号施加到LCTV的情况，从理论和实验两方面研究了光透过LCTV的偏振调制特性。图像减法通过光透过LCTV时线性偏振的近似旋转来实现。
