Abstract
Polyharmonic method of probing fiber-optic temperature and mechanical strain sensors of building structures
Incoming article date: 04.04.2019The paper presents an approach to the complex measurement of temperatureand mechanical strain for . Using a polyharmonic signal of a given shape allowed two sensors to be simultaneously polled. Temperature and mechanical strain sensors are made in the form of fiber Bragg gratings with special spectral characteristics.
