1981年8月12日美国密执安大学 N.E.Leith 教授应邀来上海光机所作“光学信息处理及其应用”为题的报告。现将报告内容摘要作一介绍。一、一般光学图象处理光学图象处理系统通常可以分成三大类。典型的光学处理系统如图1所示。1)非相干处理:照明采用非相干光源,这时输出平面上光强为 I=s*f。这里s、f是光强透过率,最后是相关输出。2)相干处理:照明用相干光源,输出平 On August 12, 1981, Professor N.E.Leith from the University of Michigan, USA, was invited to present a report entitled “Optical Information Processing and Its Applications” by Shanghai Machine. Now the summary of the report to make an introduction. First, the general optical image processing Optical image processing systems can usually be divided into three categories. A typical optical processing system shown in Figure 1. 1) Non-coherent processing: lighting using incoherent light source, then the light intensity output plane I = s * f. Here s, f is the light transmittance, and finally the related output. 2) coherent processing: lighting with coherent light source, output flat
