Estimation of the nonlinear dependence of the indications of a fiber Bragg grating on temperature and strain from experimental data

Fracture and Structural Integrity, 2022
The readings of the Bragg grating are determined based on the optical radiation reflected from it. A quantitative characteristic of this radiation is the wavelength at which the maximum power of the optical signal is achieved.

Bronchoscope Tip Localization With Learned Airway Constraints and an Open Source Simulator

Advanced Intelligent Systems, EarlyView.
BronchoLoc addresses feature‐poor bronchoscopic imaging by combining monocular video with a preoperative CT graph to estimate 3D camera location. A local tracker identifies candidate branches, while a sequence‐aware global module refines the trajectory. Demonstrating sub‐centimeter accuracy across synthetic and phantom datasets, this framework advances
