TEMPERATURE-COMPENSATED FIBER SPECKLEGRAM STRAIN SENSING WITH AN ADAPTIVE JOINT TRANSFORM CORRELATOR

摘要

A temperature-compensated fiber specklegram strain sensor with an adaptive joint transform correlator (JTC) is presented. By exploiting the dual-channel correlation of the fiber specklegram JTC, we can measure the temperature-compensated strain. Experimental results have shown that the strain sensitivity can be as high as 0.1 mu stain/1 degrees C. [References: 12]
