为获取低几何畸变高重复性的激光扫描图象，我们提出了一种基于闭环象素时钟发生器的激光扫描器非线性误差补偿方案，使用以驱动数据采集系统ＡＤ转换的象素时钟频率正比于扫描器运行的角速度，从而用采样时间间隔的非均匀性换取了采样点空间位置的均匀性。
In order to obtain a high repetitive laser scanning image with low geometric distortion, we propose a laser scanner nonlinear error compensation scheme based on a closed-loop pixel clock generator. The pixel clock frequency used to drive the AD conversion of the data acquisition system is proportional to the frequency The angular velocity of the scanner operates so that the uniformity of the spatial location of the sampling points is swapped for the inhomogeneity of the sampling interval.
