Analýza využití vláknově optického senzoru v tramvajové dopravě

Abstract

The aim of this work is to search for fiber optic interferometers in traffic applications and to practically implement and test an interferometric sensor in tramway traffic. The introductory part describes the basic principles of the functionality of optical fibers and interferometric types of sensors. Different types of interferometers and optical sensors were compared, which were used for monitoring various parameters in rail transport. Based on previously acquired knowledge and new experience, a functional sample of the Mach-Zehnder sensor, suitable also for ground-based detection of tram vehicles, was assembled. This sensor takes advantage of optical fibers such as immunity to electromagnetic interference, passivity in terms of power supply and the possibility of remotely evaluating useful information.
