Laser Scanning Imaging System Research and Development Trend Analysis

Abstract

Laser imaging technology has the advantages of good concealment and rich information of target image (such as distance, intensity and distance). It has broad application prospects in many fields such as military reconnaissance, topographic mapping and machine vision. It has become the focus and hot spot of research in many countries. This paper describes the basic principles of six kinds of laser scanning three-dimensional imaging radar systems and imaging technologies such as raster scanning, acousto-optic scanning, electro-optical scanning and galvanometer scanning, and traces and summarizes the research progress, and compares the advantages and disadvantages of various system technologies. The development trend is analyzed from the perspective of application. The conclusion is as follows: The method of realizing three-dimensional imaging by optical machine scanning is mature, with high resolution and large field of view.
