【摘要】：可调谐激光器的调制线性度和调制范围是限制调频连续波激光测距测量分辨率的主要因素.利用单个调制范围较小的可调谐激光器对单个目标进行调频连续波激光测距时,对目标进行多次测量,再将经过等光频间隔采样的信号进行信号融合可以达到提高测量分辨率的目的.该方法可以有效降低调频连续波激光测距对激光器调制范围的要求,且容易实现、系统组成简单,有利于将调频连续波激光测距引入工业大尺寸测量、空间技术、测绘等领域.
[Abstract]:The modulation linearity and modulation range of tunable laser are the main factors limiting the resolution of FM CW laser ranging measurement.When a single tunable laser with a small modulation range is used to measure a single target by frequency-modulated CW laser ranging, the target is measured several times.The signal fusion of the signal sampled by equal-frequency interval can improve the resolution of measurement.This method can effectively reduce the requirement of laser modulation range for FM CW laser ranging, and is easy to realize, and the system composition is simple, which is helpful to introduce FM CW laser ranging into industrial large-scale measurement, space technology, mapping and other fields.
