摘　　要：提出一种适合于高动态范围图象的获取和显示的强度系列成象法。改变输入图象的强度，微机控制的图象采集系统进行记录得到一组磁盘文件，形成强度图象系列。基于记录的系列图象，可以进行信息提取、变换和显示等操作。基于获得的图象系列，提出一种剪贴操作进行快速的非线性图象变换。给出对光学功率谱处理的一个实例，它相当于进行锯齿形的非线性变换。The sequential intensity imaging proposed is a new method for the acquisition and display of high dynamic range images. A sequence of intensity images is obtained by recording the images related to different intensities as disk data files in a microcomputer. All information of the input images is saved in the sequence,by which we can perform any image processing and extract any information in principle. Based on the intensity sequence,a cut-andpaste operation is proposed to perform a fast nonlinear transform. An illustration is given with an optical power spectrum. The cut-and-paste operation used is equivalent to a sawtooth transform.
