Abstract
A simple fiber optic pulse correlation sesning system was proposed for high resolution and wide dynamic measurable range temperature measurement. This sensing system uses the second harmonic generation (SHG) to detect the correlation value of the monitoring and reference pulses. The correlation value is proportional to the temperature or strain change in the monitoring fiber. By combining long and short monitoring fibers using optical switch, it is able to reach high resolution and wide range measurement. And by employing an optical time delay component, it is possible to achieve a dynamic ranges measurement.
