Analyticaland numerical examination of the imaging properties of optical diffraction tomography

摘要

The imaging properties of two-dimensional optical diffraction tomography are examined analytically and numerically. Taking into account lens aberrations in the optical system used to image the scattered light, we first derive an expression for the overall coherent transfer function. Then we use computer simulations to examine the influence of lens aberrations by comparing images obtained by a system with lens aberrations with images obtained by an aberration-free system. We also discuss the significance of systematic positioning errors in the set-up.
