摘要
基于晶体体全息角度分维复用存储机理,采用半导体抽运固体激光器取代氩离子激光器作为系统光源,设计并构建了一台小型体全息存储及相关系统。实现了基于1000幅人脸库图像的相关识别,并通过子波变换滤波预处理提取图像边缘特征,得到了较为准确的识别结果。
Abstract
Based on the principle of volume holographic storage in Fe∶LiNbO 3 crystal and angle fractal multiplexing, using diode pumped solid state laser (DPL) instead of huge ionized argon laser, a compact volume holographic data storage and correlation system was designed and constructed. The correlation of 1000 human face images is realized, and by using of wavelet transform to extract the edge character of each image, comparatively exact identification results are obtained.
