Optically recorded Fresnel zone plates have proper spatial frequency characteristics for use as a laser scanner. Such grating scanners can easily be made and can scan over large cone angles with, however, severe aberrations of the diffracted laser beam at large deflection angles. Optically recorded Fresnel zone plates for laser beam scanning are investigated, and their aberration properties are analyzed. A method for removing the wavefront error caused by this type of zone plate is discussed, and the feasibility of the method is demonstrated.
光学记录的菲涅耳波带片具有适合用作激光扫描仪的空间频率特性。这种光栅扫描仪易于制造，并且可以在大锥角范围内进行扫描，然而，在大偏转角时衍射激光束会出现严重像差。对用于激光束扫描的光学记录菲涅耳波带片进行了研究，并分析了它们的像差特性。讨论了一种消除这种类型波带片引起的波前误差的方法，并证明了该方法的可行性。
