【摘要】：激光測距技術(shù)以其非接觸測量、基準(zhǔn)光速溯源等特點(diǎn)，在各種測距技術(shù)中脫穎而出，近些年來在各領(lǐng)域中應(yīng)用廣泛。激光測距的方法又有多種，其中相位式激光測距法憑借其測程適中、測距精準(zhǔn)，在室內(nèi)、工程測距方面應(yīng)用尤為廣泛。傳統(tǒng)的相位式測距方法采用二次混頻法，結(jié)構(gòu)較為復(fù)雜，正交混頻方法的提出改進(jìn)了這一缺點(diǎn)，再結(jié)合數(shù)字同步解調(diào)測相技術(shù)，，可以更進(jìn)一步的簡化整個(gè)測距系統(tǒng)。國外已經(jīng)出現(xiàn)此類技術(shù)的測距儀，而國內(nèi)這方面的研究還不多，因此，基于正交混頻和數(shù)字同步解調(diào)的相位式激光測距儀的研究，具有很重要的價(jià)值。 本文首先介紹了激光測距技術(shù)的發(fā)展，闡述了幾種常見的激光測距的方法原理及應(yīng)用，重點(diǎn)介紹了相位式激光測距的系統(tǒng)結(jié)構(gòu)和原理方法，然后就傳統(tǒng)的技術(shù)方法提出了新的基于正交混頻和數(shù)字同步解調(diào)相位式激光測距的系統(tǒng)機(jī)構(gòu)，簡單說明傳統(tǒng)混頻方法的基礎(chǔ)上詳細(xì)闡述了正交混頻技術(shù)的原理以及測相算法。 本文的重點(diǎn)是數(shù)字解調(diào)，所以論文給出了單片機(jī)的簡介，包括功能概述、開發(fā)平臺介紹及單片機(jī)的初始化過程。詳細(xì)給出了主程序設(shè)計(jì)的內(nèi)容，包括數(shù)據(jù)采集處理模塊和上位機(jī)串行接口接收程序設(shè)計(jì)，進(jìn)行了程序仿真調(diào)試。用MATLAB對整個(gè)測相過程進(jìn)行了仿真，結(jié)合仿真圖像進(jìn)行了分析說明。最后進(jìn)行了誤差分析，并對全文做出了總結(jié)和展望。
[Abstract]:Laser ranging technology has been widely used in various fields in recent years because of its characteristics of non-contact measurement and reference light speed tracing. There are many kinds of laser ranging methods, among which the phase laser ranging method is widely used in indoor and engineering ranging because of its moderate measurement procedure and accurate ranging. The traditional phase ranging method uses the secondary mixing method, the structure is more complex, the orthogonal mixing method improves this shortcoming, and the digital synchronous demodulation and phase measurement technology can further simplify the whole ranging system. There have been many researches in this field in our country, so the research of phase laser rangefinder based on quadrature mixing and digital synchronous demodulation is of great value. This paper first introduces the development of laser ranging technology, expounds the principle and application of several common laser ranging methods, especially introduces the system structure and principle method of phase laser ranging. Then a new phase laser ranging mechanism based on quadrature mixing and digital synchronous demodulation is proposed. The principle of orthogonal mixing and phase measurement algorithm are described in detail on the basis of the traditional mixing method. The emphasis of this paper is digital demodulation, so the paper gives a brief introduction of MCU, including the introduction of function, the introduction of development platform and the initialization process of MCU. The contents of the main program design are given in detail, including the design of the data acquisition and processing module and the receiving program of the serial interface of the host computer, and the simulation and debugging of the program are carried out. The whole phase measurement process is simulated by MATLAB, and the simulation image is analyzed. Finally, error analysis is carried out, and the full text is summarized and prospected.
