Paper Abstract

A static solution to aberrations and boresight error for tilted conformal aircraft windows at different look angles is reported, which is the use of tilted and decentered fixed correctors. The principle of the static solution is discussed, and three tilted and decentered fixed correctors are designed to correct the aberrations and boresight error for a conformal window. The correctors are fixed in position between the conformal window and the gimbaled imaging system, thus requiring no moving parts. The design result shows that the predominant astigmatism introduced by the conformal window is corrected by the tilted and decentered fixed correctors at different look angles. Moreover, the boresight error for the conformal window, as a function of look angle, is also corrected by the correctors. The root mean square wavefront aberration for the final conformal window imaging system is less than 0.2 wave across the full field of regard on the visible spectrum, and the boresight error is less than 0.5' across the full field of regard.
