TESTING OF AN OPTOELECTRONIC SYSTEM OF DISTRIBUTED FIBER-OPTIC SENSORS FOR MONITORING AND DIAGNOSING THE STATE OF BUILDING STRUCTURES

This article discusses distributed systems of fiber-optic sensors based on Bragg fiber gratings for monitoring and diagnosing the state building structures, which allow periodic measurements engineering assess trends in their technical condition thereby facilitate identification possible threats. The paper presents results experimental tests an optoelectronic system gratings. distribution deformations has been estimated. study show that shape changes can be reliably detected using all installation methods optic before significant cracking occurs cement.
