| 摘 要： | 基于相位式激光测距系统的基本原理和鉴相方法,采用双调制频率的方法解决了测量距离和测距精度之间的矛盾,采用差频鉴相的方法减少电路复杂度。首次基于模块化的思想,运用Matlab的Simulink工具实现了系统的原理分析,对频域数字测相、数字同步解调测相法和自动数字测相法进行了比较。从理论上证明了实现一个高精度、快速相位式激光测距系统的可行性,为下一步实际设备研制奠定了基础。

| Abstract: | Based on a synthesis on the basic principle and the phase measurement method of laser range finder phase-shift system,the problem between range measurement and resolution measurement is solved by a twofold modulation frequency method,meanwhile,the complexity of electrocircuit is diminished by the method of difference frequency for phase measurement.Based on modularization,the basic principle of laser range finder system is first simulated by Matlab,and three principal measurement methods(The frequency digit... |
