Abstract

A single hybrid refractive/diffractive lens element is designed to replace the multiple refractive cylindrical lenses in the motionless-head parallel readout optical disk system. The new system has less elements, simplified alignment, and significantly reduced aberrations. Experimental results are presented. In addition, a design for the disk illumination element based on diffractive optics technology is introduced.
