最近Gorlitz, Lanzl和Lohmann介绍了一种光学信号处理的新方法。新方法的一个重要特点之一是采用了频率偏置,以前Macovski曾在有关文章中提到过这个概念。这篇报告是第一篇有关这个领域的独立结果的报告,并且它与实验结果相当符合,下面将作充分说明。诸如边缘增强这样一些概念,在非相干成像系统显然是被排除在外的,这是由于正 Recently Gorlitz, Lanzl and Lohmann introduced a new method of optical signal processing. One of the important features of the new method is the use of frequency offset, which Macovski used to mention in the related article. This report is the first to report on the independent results in this area and it is in good agreement with the experimental results and will be fully explained below. Concepts such as edge enhancement are clearly excluded in non-coherent imaging systems because of the
