【摘要】 介绍一种衍射光学透镜的通用设计方法,它适用于大的相对孔径和任意物像共轭距离,同时考虑了透镜基板厚度的影响。设计结果,用激光写入法加工成透镜,其成像质量达到衍射极限。更多还原

【Abstract】 A general mathod for designing diffraction lenses presented,It is adopotable to the diffraction lenses with large D/F and arbitrary conjugate distance,while effect of the sub- tracte thickness is taken into consideration.A lens thus designed was fabricated by laser writ- ing system,the imagen quality is obtained diffraction limit.更多还原
