摘要
研制了一种液晶灵巧像素光学神经元阵列器件,它利用光电混合集成技术,以非晶硅作光敏材料,以液晶实现光调制,通过特殊设计的器件结构,能实现对两束光的相减和非线性取阈等人工神经元功能。该器件具有8×8个神经元,以全并行方式工作。
Abstract
A liquid crystal neuron array with 8×8 neurons which can implement optical subtracting and thresholding parallel has been fabricated. It operates in parallel, that is, all the pixels of input are processed together simultaneously. The device is based on amorphous silicon photoconductor and features of liquid crystal rather than VLSI. So it can have higher aperture ratio, higher resolution and higher space bandwidth product.
