Phase-dispersion optical tomography [PDF]
, 2001 We report on phase-dispersion optical tomography, a new imaging technique based on phase measurements using low-coherence interferometry. The technique simultaneously probes the target with fundamental and second-harmonic light and interferometrically ...

Miniaturizing optical coherence tomography
Translational Biophotonics, 2022 Optical coherence tomography (OCT) has revolutionized ophthalmic diagnosis as a non‐invasive, cross‐sectional imaging technique in the last 30 years and hence is one of the fastest adopted advanced imaging technologies in the history of medicine.

Optical coherency matrix tomography [PDF]
Scientific Reports, 2015 AbstractThe coherence of an optical beam having multiple degrees of freedom (DoFs) is described by a coherency matrixGspanning these DoFs. This optical coherency matrix has not been measured in its entirety to date—even in the simplest case of two binary DoFs whereGis a 4 × 4 matrix.

Cross-Polarized Optical Coherence Tomography System with Unpolarized Light
Photonics, 2022 Cross-polarized optical coherence tomography offers improved contrast for samples which can alter the polarization of light when it interacts with the sample. This property has been utilized to screen pathological conditions in several organs.
