摘要
以8f系统单通道频域滤波系统为基础, 利用开关电路动态控制两块扭曲向列相场效应矩阵液晶盒的透光范围, 并以之为带通滤波器, 完成宽带、实时、稳定、灵活的光学子波变换。
Abstract
Based on an 8f single passage filtering system, using a switch circuit to control the pervirs limits of two twisted nematic mode field effected matrix addressing liquid crystal boxes and using them as a band pass filter, the wide bandwidth, real time, steady and flexible optical wavelet transform is implemented.
