Abstract: A method of designing an optical system including a dome light and coaxial light, includes: determining a distance between the dome light and the coaxial light based on a radius reduction according to a hole of the dome light; determining a size of the coaxial light based on an optical path of a light ray emitted from the coaxial light; and determining a structure of a printed circuit board (PCB) in the dome light based on an optical path through which the light ray emitted from the coaxial light is reflected by an object.

Abstract: A holographic aberration correction method and apparatus are provided. The holographic aberration correction apparatus includes: generating a plurality of sub-holograms in a hologram, as a matrix; calculating a plurality of eigenmodes and an eigenvalue and a weight corresponding to each of the eigenmodes by performing singular value decomposition on the matrix; selecting a predefined number of eigenmodes in the order of largest eigenvalues; calculating a plurality of first results which are obtained by multiplying a plurality of identical images by respective weights corresponding to the plurality of selected eigenmodes; calculating a plurality of second results by performing convolution of the plurality of first results and the plurality of selected eigenmodes, respectively; and generating an aberration-corrected hologram by adding the plurality of second results.
