SYSTEMS AND METHODS OF ABERRATION CORRECTION IN OPTICAL SYSTEMS
摘要
Described herein is a diffraction grating (1) for use in an optical system. The diffraction grating includes a substrate (2) and an array of elongate diffracting elements (3) arranged in a grating profile across the substrate. The grating profile imparts a predefined phase change to optical beams to at least partially correct the beams for optical aberrations present in the optical system.
