Paper Abstract

A simple accelerometer detection technique based on the measurement of the optical convolution between two identical fiber Bragg gratings, one used as a reference and the other used as a sensor, is presented. Theoretical calculations on sensitivity and for different tolerances on linearity are considered for uniform and apodized gratings at different reflectivity levels. Experimental measurements made with a Hopkinson bar setup where one grating is used as an acceleration sensor are presented.
