Design of an applied optical fiber process tomography system

Abstract

In this paper, a novel optical fiber process tomography (OFPT) probe is developed; in which, eight optical fiber sensor units are uniformly distributed around the cylindrical container. Each unit comprises three optical fiber collimators, one photo detector and one optical window. The window is specially designed to make the light pass through and the container waterproof. All devices in the probe are simply and easily collimated owing to the exact calculation and precision manufactory. The genetic algorithms (GAs) are used. The experimental results show that the novel OFPT system can measure gas–solid two-component distributions.
