摘要
本文讨论了计算全息激光扫描器的基本原理,详细推导出平移型二维等间距线阵扫描器的位相函数表达式和平移型二维抛物线扫描器的位相函数表达式。本文还详细介绍了上述二种扫描器的制作方法,并给出实验结果。对于等间距线阵扫描器,作者提出了一种简单易行的制作方法。
The principle of laser scanner using computer-generated hologram is discussed in this paper. Two phase function expressions of equidistant linear scanning and parabolical scanning are derived in detail. These scanner are horizontal displacement. The making methods of scanners and experiment results are given. For the equidistant linear scanner, a simple making method which can be used easily is described also.
