本专利阐述一种结构新颖的光束扫描和数字化系统,此系统可通过图像测定传动机构上的一块反射镜使旋转椭圆截面的光束偏转,从而实现光束扫描。图像测定传动机构相对扫描线的轴倾斜,这样可使传动机构控制的反射光束和扫描时的入射光束之间的相干减少到可按受的程度,以减少产生图像变形的条纹图形,从而减少被数字化图像的误差。 This patent describes a novel structure of a beam scanning and digitizing system that enables beam scanning by deflecting a beam of elliptical cross-section through a mirror on an image measuring actuator. The image measuring actuator is tilted with respect to the axis of the scanning line so that the coherence between the actuator-controlled reflected beam and the incident incident beam during scanning can be reduced to such an extent as to reduce fringe patterns that cause image distortion, Digital image error.
