Optovláknový senzor dechové činnosti lidského těla založený na kombinaci Braggovské mřížky a konvenčních kyslíkových brýlí

Abstract

This Bachelor thesis deals with the design of optical fiber sensor, using fiber Bragg grating (FBG) to measure essential vital function, namely the respiratory rate of the human. Primary use in which a sensor could be designed a verified is a magnetic resonance environment, where is needed to monitor the development of respiratory rate of human body. Optical fiber sensors, namely fiber Bragg grating, whose functional principle is in more detail explained in theoretical part of this thesis, is one of many ways, which new sensorics technologies in biomedical could take. The practical part of this thesis describes the construction of FBG sensor and its experimental measurements, which was attended by 5 volunteers. For verification of this FBG sensor, was used a reference given by the leader of this thesis. For evaluation was used a statistical method, namely Bland-Altman analysis. Bland-Altman analysis is one of the most used methods for comparing similarities between two measured signals in biomedicine, which reached the average similarity between two measured signals higher than 95%. We can than state, that experimental measurement method using designed and constructed FBG sensor was properly verified.
