CONCRETE STRAIN MONITORING WITH FABRY-PEROT FIBER-OPTIC SENSOR

摘要

The field of instrumentation is now going through new developments with the advent of fiber- optic strain gauges. Fabry-Periot is one type of fiber-optic sensing technology that can be used for microstrain measurement of concrete. However, this new generation of strain gauges first needs laboratory investigation. The Fabry-Perot type of sensor, specially designed for embedment in concrete, is evaluated. The sensor is Protected by a steel sleeve that allows its installation in concrete elements.
