本文提出了用一般的显微镜,通过投影光栅图形,获得与共焦显微镜相同效果的方法,即获得光学截面的方法。虽有类似方法的报道,但在这里提出的方法是有可能将投影的原图案去掉。将通常的光学显微镜的照明系统为光栅的投影而加以改造。只有在焦点位置的物体部分的像才成像,散焦中的深度 In this paper, a method of obtaining the same effect as a confocal microscope by projecting a grating pattern using a general microscope, ie obtaining an optical cross-section, is proposed. Although similar methods have been reported, the method proposed here is likely to remove the projected original pattern. The usual optical microscope lighting system for the projection of the grating to be modified. Only the image of the object part in the focal position is imaged, the depth in defocusing
