Optical coherence tomography- a non-invasive technique applied to conservation of paintings [PDF]

, 2005
It is current practice to take tiny samples from a painting to mount and examine in cross-section under a microscope. However, since conservation practice and ethics limit sampling to a minimum and to areas along cracks and edges of paintings, which are ...

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.

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

Scientific 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 ...
