Paper Abstract

The use of a photodetector array to process the full far-field output of a modal domain fiber optic sensor is reported. The array is linked to a laboratory computer, which reduces the data in real time and measures the transfer of power between the two lobes of the far-field output of a dual-moded fiber. The power transfer is generated by imparting a longitudinal strain to the fiber. The ratio of powers in the two lobes can be used to determine the magnitude of strain.
