摘 要: 在相干光信息处理系统中,激光斑纹的减弱,会大大提高信息处理中象的质量,本文利用旋转的镜头纸,在相干光信息处理系统中很好地减弱激光斑纹,而又在很大程度上保持了光的相干性。而以往的用旋转毛玻璃消除激光斑纹,不仅不方便。 In processing system with coherent light, the imaging qulity will be remarkably raised by reducing of laser speckles. Rotating lens tissue is used here. It does well in reducing the speckles and in retaining the spatial coherence simultaneously. In contrast, the previous method by using rotating ground glass decreases the spatial coherence. Better experimental results are obtained, and primary theoretical study is also made here.
