Nonisoplanatic imaging by phase diversity

Optics Letters, 1994
Phase diversity allows one to use multiple images with known phase changes such as defocus to learn the optical characteristics of an imaging medium and to estimate the unknown object. It is shown that the method can be extended to the case in which the optical system is nonisoplanatic; thus it can recover both the extended object and the angle ...

A Phase Unwrapping Algorithm for Interferometric Phase Images

2015
Phase unwrapping is the most complicated and unreliable stage of interferometric data processing, which is often used in remote sensing techniques. For real radar scenes, the phase unwrapping problem doesn’t have a unique solution due to phase discontinuity caused by the phase noise and aliasing.

Quantitative phase imaging: introduction

Journal of the Optical Society of America A
Quantitative phase imaging (QPI), propelled by advancements in digital holography and computational imaging, has revolutionized the ability to retrieve phase delays with high precision. Over the past two decades, the field has seen tremendous growth, contributing to numerous applications in biomedicine and material metrology, including live cell ...

Quantitative phase imaging unit

Optics Letters, 2014
A simple and cost-effective method is presented for quantitative phase imaging. A common-path lateral phase shifting interferometer is realized through attaching a compact filter set to the output port of an existing microscope. The working principles, design criteria, and limitations are also derived and explained.

Speckle imaging and hidden phase

Applied Optics, 2000
The Knox-Thompson, or cross-spectrum, method provides two two-dimensional difference equations for the phase of the object spectrum. We demonstrate that, in general, the object spectrum phase can be decomposed into a regular, single-valued function determined by the divergence of the phase gradient, as well as a multivalued function determined by the ...
