Quantitative phase imaging method based on an analytical nonparaxial partially coherent phase optical transfer function

Quantitative 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...

Rapid 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...

Quantitative phase measurement in coherent diffraction imaging.

We demonstrate high spatial resolution phase retrieval of a non-periodic gold nano-structure using the method of Fresnel coherent diffractive imaging. The result is quantitative to better than 10% and does not rely on any a priori knowledge of the sample.

Quantitative phase imaging with spectral-domain optical coherence phase microscopy

Spectral domain optical coherence phase microscopy provides high resolution quantitative phase measurement. Using a common path Fourier domain optical coherence tomography system, this technique is capable of excellent phase stability of less than 1 milliradian and high imaging speed of up to several hundred KHz Aline rate. The limitation of 2π ambiguity restriction can be overcome by the use o...
