Abstract
Thermo-optical tests were undertaken to evaluate optical effects of aircraft internal-compartment air turbulence. The turbulence sources affecting camera performance included a cold vertical vehicle window and an oscillating camera tube. A mock-up of the camera tube, compartment, and window was fabricated and interferometric data taken under simulated flight airflow and temperature conditions. Test results were initially obtained separately with a heated tube and with a simulated cold vehicle window. Test results of the combined turbulence sources indicated an rms wavefront error due to turbu-lence effects controllable in the range of 0.054 A and 0.071 A at 0.6328 um, depending on vehicle window temperature levels and compartment airflow conditions.
