色差-经常在折射望远镜的物镜上出现，是因为透镜不能把不同波长(颜色)的光聚焦到一点而形成的。
Chromatic Aberration — usually associated with objective lenses of refractor telescopes, is the failure of a lens to bring light of different wavelengths (colors) to a common focus.
从光的衍射理论和几何成象理论出发，分析研究了显微物镜焦平面附近小孔光栏的衍射和象平面位置上的成象。
From the theory of light diffraction and geometrical optics, aperture diffraction near the focal plane of microscope objectives and imaging on the image plane are studied.
在显微物镜的成象光路中，增加一块振荡反射镜，使被测线宽的放大象相对窄缝扫描，将光学边界信息转变为梯形电脉冲。
Bying adding an oscillator mirror in the imaging path, thus the enlarged image will be scanned by the narrower slit, and the optical boundary information is converted into gradient electrical pulse.
