Paper Abstract

Thermo-optical tests were undertaken to evaluate optical effects of 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 air flow 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 turbulence effects controllable in the range of 0.054λ and 0.071λ at 0.6328 μm, depending on vehicle window temperature levels and compartment air flow conditions.
