Paper Abstract

High powered microwave weapons use electric fields to overload electronics. We developed a non-intrusive sensor using a technology based on slab coupled optical sensing (SCOS). Each sensor detects the electric field component normal to the surface of the slab. By mounting two of these sensors orthogonally to each other, a more complete image of the electrical field can be obtained. One of the major hurdles of creating a multi-axial SCOS is keeping the size of the sensor small. The size is limited by (1) the size of the sensing material and (2) the ability to package the sensor to maintain its structural integrity and orientation. Good sensitivity is attained with SCOS with a length less than 3 mm and the D-fiber platform has a small core which allows for much less bending loss than standard single mode fiber. We have developed a mounting system that is heat resistant and structurally robust to protect the sensor that is extremely small when compared to traditional electric field sensors.
