An evidence-based approach to the routine use of optical coherence tomography

, 2019
Optical coherence tomography is an imaging technology that has revolutionised the detection, assessment and management of ocular disease. It is now a mainstream technology in clinical practice and is performed by non-specialised personnel in some ...

Data Compressed Photonic Time-Stretch Optical Coherence Tomography [PDF]

, 2016
Photonic time stretch enables real-time optical coherence tomography, but at the cost of extreme requirement for high-speed signal acquisition and massive data set. This work reports a data compressed real-time Fourier-domain optical coherence tomography

Optical coherence refraction tomography

Nature Photonics, 2019
Optical coherence tomography (OCT) is a cross-sectional, micron-scale imaging modality with widespread clinical application. Typical OCT systems sacrifice lateral resolution to achieve long depths of focus for bulk tissue imaging, and hence tend to have better axial than lateral resolution.

Optical sectioning in induced coherence tomography with frequency-entangled photons [PDF]

, 2018
We demonstrate a different scheme to perform optical sectioning of a sample based on the concept of induced coherence [Zou et al., Phys. Rev. Lett. 67, 318 (1991)].
