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.
如果能适时地引入梯形电路的简单介绍，则rc移相式振荡电路的振荡频率及振荡条件可以容易地求出。
If we introduce the ladder-shaped circuit simple in good time, the oscillating frequency and oscillating condition of rc phase shift oscillating can be w.
