摘要：

A simple and compact device for the monitoring I and diagnostic of fiber optic Bragg gratings, employed in optical sensor applications, was developed. The device consist of an optical fiber Bragg grating bound to a piezoelectric element. When a sinusoidal voltage is applied to the piezoelectric, the Bragg wavelength of the grating changes and the transmission spectrum swings in time. The device acts as a temporal window and can be used to interrogate a Bragg grating sensor, permiting to monitor the sensor state in real time and with very good resolution.
