Abstract

Previous work has shown nonuniformly heated windows cause distortions which affect imaging a transmitted point source as the focused spot has an angular displacement. If this angular displacement is not compensated, the processing of the imaging system’s images of the transmitted point source could be misinterpreted. The in-situ estimation technique uses LWIR pyrometry to image the inside surface of the window, material properties, and fast computational techniques. Results from this in-situ estimation technique are presented and compared with experimentally measured results. The front surface temperatures, transmitted wavefront, and angular deviation of a transmitted point source are compared.
