摘要
结合激光特性和电视扫描成像原理,提出一种二维激光光栅扫描方案,并实际建立一套光栅产生系统。通过实验得到均匀的扫描光栅,测得一组实验数据。对实验数据进行处理得到了振镜偏转角度和扫描频率之间具体的函数表达式及其图像表示,进而推导得到光栅大小和扫描频率之间的函数关系式。另外,对扫描光栅的特征参数进行了分析。
On basis of the laser characteristics and TV scanning and imaging principle, a two-dimensional laser scanning raster shaping system is put forward and an experiment system is set up in this paper. Data and even raster are obtained through the experiment. The relation between deflected angle and scanning frequency and the relation between raster and scanning frequency are deduced through the experiment data, so do. Characteristic parameters are discussed as well.
