CHANG Shan; SANG Zhi-wen; ZHUANG Ling

In order to study how to analyze spherical aberration based on the diffraction theory of wave optics,theoretical analysis and simulation were carried out.Firstly,the light intensity distribution of the image point was calculated and then the spherical aberration was further analyzed and processed.Starting from the imaging principle a circular aperture irradiated by a point source,referring to relevant documents,analytical expression of the intensity distribution of the image point only with spherical aberration on the Gaussian image plane was deduced.The diffraction mechanism and calculation and correction of spherical aberration on Gaussian image plane were analyzed and discussed.The method can handle spherical aberration more accurately.It is helpful for balancing and correction of spherical aberration in optical design and the detection and correction of spherical aberration in optical processing and electronic correction of spherical aberration in digital imaging,and conducive to promote the development of laser technology and micro-optics and micro-optoelectro mechanical systems.
