A new way of distance measurement is introduced in this paper, it is similar to traditional measurement way, and has its origination. In the new measurement way, the rough measurement of the distance is realized by countering high frequency pulses filled in discriminable phase pulses. Discriminable phase pulses go through integral circuits, and then are sampled by Analogue Digital Converter, so the accurate measurement of the system is obtained by the sampling value.

本文提出了一种新的测距方法，该方法与常规相位测距仪比较，既有相似之处也有其创新之处，常规相位测距仪一般使用多波长测尺频率组合、差频数字测相的方法，本系统虽然也采用多波长测尺频率组合，但并不采用差频数字测相，该方法摒弃了传统的内外光路的切换方式及电路的混频，粗测采用对鉴相脉冲填充高频脉冲的办法实现，精测则利用鉴相脉冲对积分电路进行积分，然后由ADC 对积分电平进行转换，通过对ADC 的输出值的计算处理实现精测。

Open Linear Encoder includes main grating scale and optical encoder head. This optical encoder head includes LED light source, optical detector module, and secondary phase-grating. LED light will pass through the plano-convex lens and produces parallel light. As the parallel light pass through secondary grating, the quadratic image display on the main grating scale. And the Moire interference will be reflected from the main grating scale and detected by optical detector module, as there is a relative shift between the main and secondary grating. From detecting the periodic sinusoidal signal with phase difference 90°, the period represents the grating pitch, using the counter to detect the number of periodic signals to get the displacement, and we can adapt the technology of electron subdivide further to increase the resolution of measurement .
