Structural Design Of Laser Scanning Probe System

Firstly, this article summarizes the three-dimensional laser scanning technology and laser imaging detection theory, and as a theoretical basis, to propose a set of laser probe scanning system design solution. Laser probe scanning system architecture consists of three parts: laser ranging part, mechanical scanning part, data acquisition and processing part. The part of laser range uses high-frequency laser range finder to measure the distance information of the target shape and get a lot of point cloud data. Mechanical scanning part includes high-speed rotary table, high-speed transit and related structure design, in order to realize the whole system should be carried out in accordance with the design of scanning path on the target three-dimensional laser scanning. Data processing part mainly by FPGA hardware with LabVIEW software to design a core, to process the point cloud data collected by the laser range finder at the high-speed and fitting calculation of point cloud data, to establish a three-dimensional model of the target, so laser scanning imaging is realized.The laser probe scanning system uses a laser range finder with high speed turntable, high-speed rotating mirror and other structures makes the whole system to achieve fast continuous three-dimensional laser scanning. And by the related mechanical structure design of the scanning system solved mechanical system response frequency and ranging pulse frequency mismatch problem, to improve the efficiency of the high-frequency pulse ranging scanning laser.
