The Choroid and Optical Coherence Tomography

open access: yesTürk Oftalmoloji Dergisi, 2016
The choroid is the most vascular tissue in the eye and it plays an important role in the pathophysiology of various common chorioretinal diseases such as central serous retinopathy, age-related macular degeneration and degenerative myopia.

Cross-Polarized Optical Coherence Tomography System with Unpolarized Light

open access: yesPhotonics, 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.

Optical tomography dynamics induced by qubit-resonator interaction under intrinsic decoherence

open access: yesScientific Reports, 2022
A superconducting circuit with a qubit and a resonator coupled via a two-photon interaction is considered. When the resonator is initially in a superposition of coherent states, optical tomography and quantum coherence dynamics are examined in the ...
