【摘要】：可調(diào)諧激光器的調(diào)制線性度和調(diào)制范圍是限制調(diào)頻連續(xù)波激光測(cè)距測(cè)量分辨率的主要因素.利用單個(gè)調(diào)制范圍較小的可調(diào)諧激光器對(duì)單個(gè)目標(biāo)進(jìn)行調(diào)頻連續(xù)波激光測(cè)距時(shí),對(duì)目標(biāo)進(jìn)行多次測(cè)量,再將經(jīng)過(guò)等光頻間隔采樣的信號(hào)進(jìn)行信號(hào)融合可以達(dá)到提高測(cè)量分辨率的目的.該方法可以有效降低調(diào)頻連續(xù)波激光測(cè)距對(duì)激光器調(diào)制范圍的要求,且容易實(shí)現(xiàn)、系統(tǒng)組成簡(jiǎn)單,有利于將調(diào)頻連續(xù)波激光測(cè)距引入工業(yè)大尺寸測(cè)量、空間技術(shù)、測(cè)繪等領(lǐng)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.
