Fig. 1: Optical setup and working principle of Wolf phase tomography (WPT).
From: Wolf phase tomography (WPT) of transparent structures using partially coherent illumination
a WPT optical setup. The spatial light interference microscopy (SLIM) add-on module is mounted to the output camera port of a phase-contrast microscope. This module shifts the phase between the incident and scattered field with π/2 increments using the SLM. The interference patterns are recorded by the camera. b Spectrum, c autocorrelation, and d second-order derivative of the autocorrelation of the halogen source measured by the spectrometer. e Three phase-shifted frames of 2-μm polystyrene beads are acquired using the SLIM module (×63/1.4 NA)
