Paper Abstract

This paper studies the optical diffraction, defocus, and sampling effects on the high speed imaging system. Through detailed analysis, we formulate the point spread function (PSF) and optical transfer function (OTF) which characterize the optical system in the spatial and frequency domain respectively. With the approximate priori knowledge of their PSF, we propose two integer focus operators and analyze their OTFs in association with those of Laplacian and the optimal focus operator. The experimental results and comparison validate our theoretical investigation.
