Paper Abstract

A new approach to the measurement of D.C. parameters using optical fiber interferometry is reported. The technique is based on a sensing configuration in which displacement, or linear strain in a transducer, is nonlinearly transposed into fiber strain and thus optical phase shift. An accelerometer based on the technique exhibits a detection sensitivity better than 1 μg and a dynamic range > 2x106.
