Abstract

We propose a method that recovers phase from a stack of through-focus intensity images taken with a partially coherent microscope employing illumination of any arbitrary source shape. Our algorithm uses a Kalman filtering approach, which is fast, accurate and robust to noise. We validate the method in simulation and with experimental data taken on a commercial microscope with varying condenser apertures in Köhler geometry.
