Infrared Fiber Bundles Based on Silver Halide Crystals for Monitoring and Control Systems in Heat and Power Engineering

Abstract

We develop and fabricate ordered fiber bundles based on silver halide crystals. They are thin, flexible, and non-hygroscopic. These bundles allow detecting temperatures in the interval of -130 – 900 oC with good spatial resolution and can be embedded in monitoring and control systems. To show their suitability for infrared thermography in the heat and power engineering, the temperature distribution over the height of a gas turbine blade was measured using an IR thermographic system contained a linear silver halide fiber bundle.
