摘　　要：提出利用单个电子捕获 (ET)器件及对输入模糊逻辑变量进行面积编码的方法实现光学并行模糊逻辑操作。本方案采用单行编码方式 ,所以输出图像的像素行间没有间隙 ,图像依然是完整的。基于电子捕获器件的存储和擦除特性 ,两个模糊图像间的所有模糊逻辑函数都可以通过对输入编程来实现。此系统不需要取阈装置、透镜阵列和解码板 ,因而具有高速和大信息量的特点 ,且可紧凑化。An optical system using a single electron trapping (ET) device with area encoding of input fuzzy variables and negations is proposed to perform fuzzy logic operations in parallel. In this scheme, each encoding cell is only composed of one encoding cell so that the resultant pattern is still the image in which there is no space between any two pixel rows. Based on the storage and erasure characteristics of the ET device, all of the fuzzy logical functions of two images can be implemented in parallel and spatial-invariant by programming the illumination form of data arrays. No thresholding device, lens array and decoding mask is needed, therefore, this system exhibits high operation speed and large information throughout. The system can be compact. The experimental results are also given.
