Multi-Channel Sparse-Frequency-Scanning White-Light Interferometry with Adaptive Mode Locking for Pulse Wave Velocity Measurement

Photonics, Journal Year: 2025, Volume and Issue: 12(4), P. 316 - 316

Published: March 28, 2025

Fiber-optic Fabry–Pérot (F–P) sensors offer significant potential for non-invasive hemodynamic monitoring, but existing sensing systems face limitations in multi-channel measurement capabilities and dynamic demodulation accuracy. This study introduces a sparse-frequency-scanning white-light interferometry (SFS-WLI) system with an adaptive mode-locked cross-correlation (MLCC) algorithm to address these challenges. The leverages telecom-grade semiconductor lasers (191.2–196.15 THz sweep range, 50 GHz step) Fibonacci-optimized MLCC achieve real-time cavity length at 5 kHz. Compared normal algorithm, the reduces number of computational iterations by 57 times while maintaining sub-nanometer resolution under perturbations. Experimental validation demonstrated carotid–radial pulse wave velocity 5.12 m/s healthy male volunteer. work provides scalable cost-effective solution cardiovascular monitoring applications point-of-care testing (POCT) telemedicine.

Herramienta asistencial para el diagnóstico postural en sedestación en personas con movilidad reducida

Revista Iberoamericana de Automática e Informática Industrial RIAI, Journal Year: 2024, Volume and Issue: unknown

Published: Dec. 19, 2024

El diagnóstico postural puede servir para la determinación del estado funcional de los pacientes con baja movilidad. Hasta fecha, este se ha realizado por medio cuestionarios subjetivos y forma no continuada. Para solventar esto, en trabajo presenta una herramienta asistencial monitorización objetiva. Así, un dispositivo bajo coste, enfocado a población movilidad, basado el uso sensores fuerza que permiten monitorizar su distribución peso sedestación. A partir datos recopilados han desarrollado dos herramientas diagnóstico, centrada identificaci´on postural, segunda anomalías patrón cada paciente. De esta forma, solo estimar grado debilitamiento muscular, sino también posibles cambios funcional. Los resultados obtenidos muestran desarrollada gran eficacia, tasas acierto encima 90%.
