IR Thermographic System Supplied with an Ordered Fiber Bundle for Investigation of Power Engineering Equipment and Units
Abstract
In this article, the authors propose an IR imaging system, supplied with an IR bundle of ordered silver halide fibers, for the acquisition of 2D temperature field distribution in hard-to-reach places. We assessed crosstalk between neighboring individual fibers of the bundle, carried out calibration of the IR imaging system, and determined modelled defects using this system. The results showed the applicability of the system for the inspection and investigation of power engineering units.
Keywords: IR fiber bundles, IR thermography, internal defects detection
