摘要
将数字全息术用于粒子场测试,数字全息术中采用电荷耦合成像器件CCD记录全息图。用基于局部曲面拟合的方法矫正图像背景,详细论述了基于粒子场全息图像的背景矫正、中值滤波等降噪技术,并对小波分析去噪的方法进行了探讨。
The diffraction patterns produced by the particles are directly recorded by a conventional CCD camera.Correcting the background of image by part curved surface fitting technology,describes in detail background correcting and median filter de-noising technology of the diffraction patterns,and discussing de-noising methods by wavelet analysis technology.
