Partially coherent phase microscopy with arbitrary illumination source shape
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 ...
متن کاملRapid quantitative phase imaging for partially coherent light microscopy.
Partially coherent light provides promising advantages for imaging applications. In contrast to its completely coherent counterpart, it prevents image degradation due to speckle noise and decreases cross-talk among the imaged objects. These facts make attractive the partially coherent illumination for accurate quantitative imaging in microscopy. In this work, we present a non-interferometric te...
متن کاملQuantitative phase imaging with partially coherent illumination.
In this Letter, we formulate a mathematical model for predicting experimental outcomes in quantitative phase imaging (QPI) when the illumination field is partially spatially coherent. We derive formulae that apply to QPI and discuss expected results for two classes of QPI experiments: common path and traditional interferometry, under varying degrees of spatial coherence. In particular, our resu...
متن کاملPhase retrieval of the full vectorial field applied to coherent Fourier scatterometry.
Coherent Fourier scatterometry is an optical metrology technique that utilizes the measured intensity of the scattered optical field to reconstruct certain parameters of test structures written on a wafer with nano-scale accuracy. The intensity of the scattered field is recorded with a camera and this information is used to retrieve the grating parameters. To improve sensitivity in the paramete...
متن کاملStorage and retrieval of correlation functions of partially coherent fields.
A new method is described for determining the two-point equal-time coherence function (the mutual intensity) and the two-point equal-time intensity correlation function of partially coherent fields. The method is reminiscent of conventional holography but differs from it in several important respects.
