Abstract
Abstract An imaging system for a missile rotating about a principal axis (A) has an imaging lens arrangement 6 and a detector arrangement 8 situated in the focal plane of the imaging lens arrangement for the generating of electric image signals which are processed while the respective rotating position of the missile is taken into account to achieve a high image definition in a manner that is very simple technically as well as with respect to signal processing techniques, the detector arrangement and the imaging lens arrangement with their optical axis are arranged to carry out the same motion as the missile while rotating about the principal axis of the missile, and the detector arrangement comprises one or several detector row(s) which extend from the image field edge of the imaging lens arrangement toward the missile axis.
