The Automated Vestibular Rehabilitation System: Normative Data From a Machine Vision‐Guided Platform

The Laryngoscope, EarlyView.
The Automated Vestibular Rehabilitation System (AVRS) is a machine vision‐based tool designed to increase accessibility to vestibular rehabilitation therapy by automating exercise delivery and tracking head‐eye movements in real time. In n = 40 healthy adults, the AVRS accurately measured vestibulo‐ocular reflex (VOR) gain values near physiologic norms

Laser Stabilized to a Fiber Interferometer With Close‐To‐Zero Temperature Sensitivity

Laser &Photonics Reviews, EarlyView.
A laser stabilized to a hollow‐core fibre interferometer is presented. The interferometer is designed to have near‐zero temperature phase‐sensitivity. Laser stabilized to this interferometer put in a non‐vacuum environment achieves ±550 kHz frequency variation over 100 h and an Allan deviation of 2 × 10−14τ, which is comparable to miniature ULE ...

NIR/VIS Dual‐Comb Spectroscopy Comparing High and Low Repetition Rate Regimes

Laser &Photonics Reviews, EarlyView.
This work compares dual‐comb spectroscopy at lower and higher repetition rates, emphasizing the inherent trade‐off between spectral and temporal resolution. The 80 MHz system provides high‐resolution spectra suitable for analyzing complex molecular structures, whereas the free‐running 1 GHz platform enables fast measurements for real‐time trace gas ...
