Abstract
Segmented windows for military aircraft introduce several optical effects into airborne electro-optical sensor imagery. A diffraction-based computer code has been written to calculate these effects and predict impacts on installed sensor performance. Experimental validation of the code agrees to within 3 percent. The window segments are seen to effectively divide the sensor pupil into separate optical apertures sharing a common focal plane. Extremely tight optical wedge tolerances are indicated for high-resolution sensors. Performance predictions for various pupil splitting geometries are shown, both for polychromatic incoherent sensor imagery and coherent laser radiation. Effects of varying differential wedge on sensor imagery are shown.
