Higher Speed Demodulation of Fiber Grating Sensors

Abstract

For very high-speed events such as ballistics testing strain measurement speed is not limited by the response of the fiber grating sensor but rather the demodulation system used. This paper focuses on a current 10kHz fiber grating demodulator used to support impact and ballistics testing of a composite panel. It also explores the next generation demodulator pushing the limits of speed upwards of 3Mhz.
