Abstract
In recent years, high-resolution optical microscopy has developed rapidly and its resolution has been increasing, and the point spread function directly affects the resolution. In this paper I generate a point spread function for an aperture-based imaging system (a lens with a shaped aperture). I also generate a flat-top signal (uniformly illuminated circular unobstructed aperture) and a pupil-masked two-dimensional Fourier transform and pass through an inverse oscillation filter, and compare them by analyzing the centrality of the spectrum, frequency distribution, and energy distribution.
