ABSTRACT:
Photons from nuclear radiation are absorbed by fiber optics and the mater of the fibers have their energy levels elevated causing fluorescence. The fluorescence is a noise component which interferes with light signals axially passing through the fiber optics. By using a narrow bandwidth interference optical filter, centered about the communication frequency, the noise interference may be substantially reduced so that an acceptable signal-to-noise ratio is achieved. A tuned optical filter will compensate for drift of the center communication frequency.
