NOVA-Temperature Sensing technology is a patented application based on novel range-resolved interferometric signal processing technique.
A temperature gradient applied to a NS (NOVA-Segment), that is the strain sensing element, induces a phase change to the carrier signal of the reflectors.
In detecting the phase change from the reference fibre cleaved end, it is possible to quantify the temperature change and so the integral result of the temperature gradient applied along the segments.
