Abstract

Numerical modeling is used to show that the sensor described herein is capable of an angular resolution of 0.1° when used in a small, position-sensitive spark sensor with an angular field of view of ±6.5^∘. A spectral radiation converter in the form of a thin, high-persistence luminescent polymer film can be used to increase the sensor’s spatial resolution and sensitivity to brief electrical discharges. Testing with a prototype spark sensor indicated that the spatial resolution was sufficient to reliably determine the spatial location of the spark. These results can be used in the development of emergency warning equipment.
