摘要
在一般应用单片机的莫尔条纹细分电路中增添一个模拟乘法器和少量的外围元件，能明显降低因两路信号幅值不等引起的测量误差，同时使分辨力提高一倍。
When an analog multiplier and a few elements are added to Moire Fringe interpolation circuit of the Single Chip Microcomputer system the error cause4 by the amplitude difference between the two pathes of the Moire Fringe signal is reduced distinctly. The resolution of this circuit is one time higher than that of the past.
