Moreover, in an enclosed cavity, the multiple reflections of the signal before reaching the camera can lead to a geometry-dependent apparent increase in emissivity. In this work, we describe a novel approach for solving this problem in the context of measurements within a model aircraft engine combustion chamber. By using thermocouples and a multi-spectral camera, we experimentally validate our radiometric model for the cavity. We first show how to evaluate the amplification factor of a cavity using numerical tools, and we then use these results to apply corrections on the camera signals for in-band radiance (IBR) measurements. As a non-invasive and non-destructive technique, this approach can be used to monitor in real time the evolution of the temperature and emissivity over a large temperature range. As a specific example, we present and compare values measured by the camera and thermocouples inside the combustion chamber. Following the calibration step, we determine the emissivity and temperature distribution of the entire scene. The calculations are compared across 3 different wavebands to ensure their validity, with a difference lower than 2 %. Finally, we showcase the importance of assessing the <em>in situ</em> emissivity of a surface, which can change drastically with a large temperature variation and in a harsh environment.

The quantitative relationship between surface damage variables and internal damage variables at different loading stages of granite is established. Specifically, the relationship is exponential during the plastic deformation stage, while in the failure stage, the relationship becomes parabolic, characterized by a simultaneous surge phenomenon in both types of damage. Furthermore, the quantitative relationship between infrared radiation temperature and principal stress is established, revealing that the correlation between infrared radiation temperature and principal stress is a positive linear relationship with a linear correlation coefficient exceeding 0.95.
