Optical Remote Sensing of Environmental Pollution and Danger by Molecular Species Using Low-Loss Optical Fiber Network System

  • Humio Inaba
Part of the Springer Series in Optical Sciences book series (SSOS, volume 39)

Abstract

The recent progress in fabrication and cabling techniques for extremely low-loss optical fibers in the near infrared region has stimulated considerable interest in the practical implications of the technology. The present excitement is due to the tremendous possibility that optical fiber technology could eventually find application not only to long distance optical communication and image transmission but also to remote measurement and control as those requireed in various scientific and industrial fields.
