摘要
新型图像扫描器具有较高的响应频率 ,可以实现高速扫描。在研究扫描器运动参数分离的基础上 ,利用对称放置的半导体位置探测器建立了扫描器的多运动参数测试系统 ,提出了光电二维位置传感器的非线性修正和补充方法 ,实现了四路模拟信号的 DMA传送 ,提高了测试的速度和精度 ,实现扫描器在高频运动时的多运动参数测试。
The new type of image scanner has higher frequency response and the scan with high speed can be realized. Based on the study of the movement parameter separation of the scanner, the multi-parameter test system is established by the use of the semi-conductor probes placed in a symmetry way. The nonlinear revision and the supplement method for the photo-electric 2D position probe are proposed. The DMA transmmision of the 4 channel analogy signal are realized. The test speed and accuracy are arised. The test of movement parameters is realized during the high frequency movement of scanner.
