La FTTO signifie Fiber To The Office, en référence à la FTTH (Fiber To The Home) déployée en France chez les particuliers. Le principe de la FTTO est de câbler un bâtiment tout en fibre optique, d'éliminer au maximum tout câble en cuivre et de poser des micro-commutateurs dans chaque bureau (goulotte ou à côté), au plus près des machines. La connex...
Les capteurs de température à fibres optiques possèdent de nombreux avantages tels que leurs faibles tailles et poids ainsi que leurs immunités à une large bande du spectre électromagnétique. La technologie des réseaux de Bragg inscrits sur fibre optique présente les mêmes avantages et ils sont de plus ultra-rapides, permettant de mesurer la tempér...

Nanobiosensors (NBSs) are a class of chemical sensors which are sensitive to a physical or chemical stimulus (heat, acidity, metabolism transformations) that conveys information about vital processes. NBSs detect physiological signals and convert them into standardized signals, often electrical, to be quantified from analog to digital. NBSs are cla...

Three types of plasmonic sensors are applied for the detection of five types of human-liver tissues (normal N, metastatic MET, non-cancerous metastatic NMET, hepatocellular carcinoma HCC and non-cancerous hepatocellular carcinoma NHCC). The first type of the fiber with seven layers is made by a ZBLAN core surrounded by NaF, silicon, silver, graphen...

We propose a novel localized surface plasmon resonance (LSPR) sensor system based on polymer material. The proposed LSPR system consists of the incident medium with low-loss polymer waveguide and the chemically immobilized plasmonic nanoparticles for on-chip LSPR sensing. Because of low coupling efficiency of conventional methods, usually intricate...
Diplomová práce se zabývá klasifikací zvukových signálů získaných z optických vláken. Cíle dosahuje pomocí analýzy problému, návrhu architektury, implementace klientské a serverové aplikace. Dále se práce zabývá testováním klientské aplikace. Výsledná aplikace je schopná zpracovávat různé typy signálů v předem stanoveném formátu a klasifikovat je. ...

Fiber photometry is a sensitive and easy way to detect changes in fluorescent signals. The combination of fiber photometry with various fluorescent biomarkers has substantially advanced neuroscience research over the last decade. Despite the wide use of fiber photometry in biomedical fields, the lack of a detailed and comprehensive protocol has lim...

Salivary urea was reported to be a useful biomarker to reflect the blood urea nitrogen in chronic kidney disease patients. However, as a new biomarker, enormous clinical trials are required to define the intended-use and to verify the specification. In this report, we demonstrated a low-cost easy-operated real-time sensing system (optical fiber-ure...

Computational neuroscience has been widely used in fiber optic sensor signal output. This paper introduces a method for processing the Surface Roughness Fiber Optic Sensor output signals with a radial basis function neural network. The output signal of the sensor and the laser intensity signal as the light source are added to the input of the RBF n...
