Description

ABSTRACT:
A system for automatic and real time detection of the presence or absence of a substance in an environment by monitoring variations in light energy transmitted through an optical fiber having a specially processed sensitive probe area. The sensitive probe area is positioned on, about or within the environment where a substance is to be detected. Because of differences in optical indices of refraction and energy absorption characteristics of different substances, the presence of different substances at the processed sensitive area will cause different proportional and characteristic attenuation of the light energy passing through the optical fiber. Changes in light energy transmission can be interpreted automatically to provide an indication of the condition of an environment.
