Fourier transform infrared (FT-IR) spectroscopy is proving to be reliable and economical for the quantification of many gas-phase species during testing and development of gas turbine engines in ground-based facilities such as sea-level test cells and altitude test cells. FT-IR measurement applications include engine-generated exhaust gases, facility air(More)
Since digital holography was first developed in the early 1990s, camera pixel pitch has decreased considerably. In particular, image sensors targeting the mobile phone market now feature very small pixels with high pixel count. These image sensors, though inexpensive, can be used in digital holography, taking advantage of their fine pixel pitch. This paper(More)
This paper announces the implementation of a long wavelength infrared camera to obtain high-speed thermal images of an aircraft engine's in-service thermal barrier coated turbine blades. Long wavelength thermal images were captured of first-stage blades. The achieved temporal and spatial resolutions allowed for the identification of cooling-hole locations.(More)
