Abstract

Quantitative thermographic monitoring techniques are described for high-temperature testing applications. Techniques already used in arc-jet testing are described, along with other techniques used in wind tunnel test facilities which can be applied to solve problems related to quantifying thermographic data from arc-jet testing. These include methods to obtain reliable values for the effective optical properties, the surface emissivity, and the window or media transmittance. In addition, methods are discussed to obtain the required corrections for the spatial resolution, viewing angle, extraneous reflections, etc. and calibrations under conditions close to the test configuration.
