Project Description

This program aims to develop a new type of low cost, robust metal-ceramic coaxial cable (MCCC) Fabry-Perot interferometer (FPI) sensor and demonstrate the capability of cascading a series of FPIs in a single MCCC for real-time distributed monitoring of temperature up to 1000 degrees Celsius. The sensor will be operated in various gas environments relevant to coal-based power production to examine its stability in practical applications.

Project Benefits

Research activities under this project may address the fundamental issues associated with sensor material design, synthesis, and integration as well as the instrumentation and algorithmic integration for sensor devices and measurement systems. It could provide reliable, highly sensitive, low cost distributed sensing over large distance/area.
