光学扫描装置，打印设备，调整振动反射镜的振幅的方法。
Optical scanning device, printing apparatus, and method for adjusting oscillation amplitude of an oscillating mirror.
满足夫琅和费远场条件的两个物体，z值大的物体将被环数少的菲涅耳波带板扫描，具有小而平直的孪生像噪声振幅；
In the far-field, the further object scanned by FZP with fewer fringes has flatter and lower amplitude of twin-image noise for reconstructed image.
