Phase-conjugate optical coherence tomography [PDF]
, 2006 Quantum optical coherence tomography (Q-OCT) offers a factor-of-two improvement in axial resolution and the advantage of even-order dispersion cancellation when it is compared to conventional OCT (C-OCT).

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.

Der Ophthalmologe : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 2004 Optical coherence tomography (OCT) is a high-resolution imaging method for in vivo investigation of the human skin. In cross-sectional images of several millimeters length with a penetration depth of the light signal into deeper parts of the dermis, architectural details of the upper skin layers can be assessed and monitored non-invasively over time ...

Time- and frequency-domain polariton interference
, 2012 We present experimental observations of interference between an atomic spin coherence and an optical field in a {\Lambda}-type gradient echo memory. The interference is mediated by a strong classical field that couples a weak probe field to the atomic ...

Density-matrix theory of the optical dynamics and transport in quantum cascade structures: The role of coherence [PDF]
, 2009 The impact of coherence on the nonlinear optical response and stationary transport is studied in quantum cascade laser structures. Nonequilibrium effects such as pump-probe signals, the spatio-temporally resolved electron density evolution, and the ...

Optical Coherence Tomography (OCT): Principle and Technical Realization
High Resolution Imaging in Microscopy and Ophthalmology, 2019 Optical coherence tomography (OCT) is a non-invasive technique for cross-sectional tissue imaging. It typically uses light in the near-infrared spectral range which has a penetration depth of several hundred microns in tissue.
