摘要:
An optical scanning system utilizing a spinner component having plane diffraction gratings thereon and a focusing lens adapted to compensate for linearization errors at the recording plane. The lens includes optical elements which compensate for the 3rd and 5th order coefficients of distortion associated with this type of diffraction scanning component.
