Digital holography for quantitative phase-contrast imaging
Optics Letters, 1999We present a new application of digital holography for phase-contrast imaging and optical metrology. This holographic imaging technique uses a CCD camera for recording of a digital Fresnel off-axis hologram and a numerical method for hologram reconstruction.

Full-field quantitative phase imaging
SPIE Proceedings, 2008Full-field quantitative phase imaging provides useful endogenous contrast in a variety of biological specimens where contrast from other natural sources is small and the use of exogenous materials is undesirable. While the concepts of interferometric microscopy are simple and have long been known, diffculties in implementation have prevented this ...

Time Stretch Quantitative Phase Imaging
2017Label-free cell analysis is essential to personalized genomics, cancer diagnostics, and drug development as it avoids adverse effects of staining reagents on cellular viability and cell signaling. However, currently available label-free cell assays mostly rely only on a single feature and lack sufficient differentiation.

Quantitative Phase Imaging Using Hard X Rays
Physical Review Letters, 1996The quantitative imaging of a phase object using 16 keV x rays is reported. The theoretical basis of the techniques is presented along with its implementation using a synchrotron x-ray source. We find that our phase image is in quantitative agreement with independent measurements of the object.

Quantitative phase imaging by optimized asymmetric illumination
Applied Optics, 2017We have presented a simple approach for quantitative phase imaging by optimizing asymmetric illumination of a conventional microscope. With this illumination, the light intensity modulation accompanying refraction at the surface profile of phase objects occurs, and "phase-gradient information" can be derived by detecting it.

Coded aperture pair for quantitative phase imaging
Optics Letters, 2014This Letter proposes a novel quantitative phase-imaging approach by optically encoding light fields into a complementary image pair followed by computational reconstruction. We demonstrate that the axial intensity derivative for phase recovery can be well estimated by a coded-aperture image pair without z axial scanning.

Complex Speckle Illumination for Quantitative Phase Imaging
2025 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC)Speckle patterns generated by multimode fibers (MMFs) are often seen as a challenge in imaging, particularly when precise control of illumination is needed [1]. In this work, we focus on a different perspective: speckles from MMFs can be highly beneficial, offering a diversity of random illumination patterns.
