摘要
描述了一种采用相位式激光测距提高测距精度的方法,给出了采用相位式进行激光测距的原理,指出了采用单一频率进行测距时存在的矛盾,从而提出了在单一频率的基础上添加多个辅助频率进行测距,分析了采用多个辅助频率进行相位激光测距的原理,并对采用该方法进行了精度分析。从分析的结论看,采用的辅助频率个数越多,则越能提高测距精度,同时该方法还能提高测量范围,解决了单一频率测量时的矛盾,达到了测距时高精度、大范围的工程应用要求。
This paper proposes a new method to improve measurement precision, which is called phase laser measuring method. After explaining the working theory of this new method, the paper points out the contradiction when single frequency measurement method is adopted, introduces a solution of adding multiple aid frequencies to single frequency when conducting laser measuring, and analyzes the working theory and precision of this solution. From the analysis, the paper concludes that the more aid frequency is adopted, the more precise the measuring result will be. In addition, the new method can enlarge measuring scope. Therefore, in application of project, the new method better meets the requirement of high precision and large scope.
