摘要
文章介绍了一种一维光学相关器,在其傅里叶平面内,将液晶电视( L C T V) 编码成单极二元纯位相滤波器用于图像实时编码或解码。
One-dimensional optical correlator using a liquid crystal television (LCTV) in the Fourier plane is described.The LCTV is used to encode unipolar binary phase-only filters for real-time scrambling/descrambling images.Preliminary optical experimental results are given.
