Paper Abstract

Blackbody radiation sensors are well known for measuring high temperature in harsh environments. Conventionally, these sensors require materials with high and stable emissivity. Any dimensional changes or shifts in the emissivity over the lifetime of the device would degrade sensor performance. This paper presents a new temperature sensing concept where thermal radiation is integrated over the length of an optical waveguide. Under some easily attainable conditions, it is shown that the new sensor output is independent of both the emissivity of the material and the length of the integrating waveguide.
