Modeling and implementation of a position-sensitive fiber optic spark sensor with spectral radiation converter

Abstract

Through numerical modeling of the optical part of the developed position-sensitive fiber-optic spark sensor with a spectral radiation converter, it was demonstrated that the sensor’s angular resolution in the range of ±18° is 3°. The spectral characteristics of the fluorescent glass plate with silver molecular clusters, which was used as the radiation converter in both numerical modeling and the experimental prototype, were investigated. Based on the developed optical sensor design, an experimental prototype was assembled. Testing of the prototype showed that it is capable of etecting sparks at a distance of 1000 mm within an angular range of ± 18° with an angular resolution of 3°. The results obtained from modeling and prototype testing are consistent and can be utilized in the development of sensors and emergency systems.
