TLDR
In this article, the non-linearity of the 1D scanning functions, which are the output signals of a laser scanner, is analyzed for the three most common input signals (triangular, sawtooth, and sinusoidal), for which the effective duty cycle/time efficiency (of the output) was modeled using optical coherence tomography (OCT) imaging, in contrast to the theoretical duty cycle (of input).About:

TL;DR: It is concluded that OCT is more appropriate than radiography in all applications, except bone-related investigations and periodontitis that demand data from higher-penetration depths than possible with the current level of OCT technology.

Quantitative assessment of rat bone regeneration using complex master-slave optical coherence tomography
TL;DR: The study demonstrates that OCT can assess quantitatively the positive impact of LLLT on bone regeneration, and the capability of an in-house developed multimodal complex master slave (CMS) enhanced swept source (SS) optical coherence tomography (OCT) imaging instrument to analyze the increase in the quantity and the improvement of the quality of newly-formed bone using low level laser therapy (LLLT).

Exact Scan Patterns of Rotational Risley Prisms Obtained with a Graphical Method: Multi-Parameter Analysis and Design
TL;DR: In this article, the authors developed a graphical method to determine and characterize, using a commercially available mechanical design program (for example CATIA V5R20 (Dassault Systems, Paris, France)), the exact scan patterns of rotational Risley prisms.

Optical Coherence Tomography Investigations and Modeling of the Sintering of Ceramic Crowns.
TL;DR: The aim of this work is to monitor the quality of sintering processes using an established biomedical imaging technique—optical coherence tomography (OCT) and to propose the use of OCT, a non-destructive method that brings objectivity for such assessments, focusing on metal ceramic dental prostheses.

Risley-prism-based multi-beam scanning LiDAR for high-resolution three-dimensional imaging
TL;DR: In this article , a unified LiDAR point cloud processing framework is developed, where the multi-mode integrated filtering method is proposed for outlier removal using point cloud characteristics, and a coarse-fine coupled strategy is also formulated to combine statistical modeling with iterative optimization for multi-channel point cloud registration.

TL;DR: OCT as discussed by the authors uses low-coherence interferometry to produce a two-dimensional image of optical scattering from internal tissue microstructures in a way analogous to ultrasonic pulse-echo imaging.

TL;DR: Optical coherence tomography (OCT) has developed rapidly since its first realisation in medicine and is currently an emerging technology in the diagnosis of skin disease as mentioned in this paper, where OCT is an interferometric technique that detects reflected and backscattered light from tissue.

High-speed wavelength-swept semiconductor laser with a polygon-scanner-based wavelength filter
TL;DR: Ultrahigh-speed tuning of an extended-cavity semiconductor laser is demonstrated, which is more than an order of magnitude faster than previously demonstrated and is facilitated in part by self-frequency shifting in the semiconductor optical amplifier.

TL;DR: Various multimodal imaging modalities with OCT incorporated are reviewed, in that these multi-modal implementations can synergistically compensate for the fundamental limitations of OCT when it is used alone.
