Abstract

High resolution photography from aerospace vehicles requires that there be no relative motion between the film and the image of the scene being photographed during the time of exposure. Such image motion occurs as a result of translation and angular rotation of the vehicle relative to the scene being photographed. Present generation aerospace camera systems employ a two part solution to the problem of image stabilization. A stabilized mount is used to provide isolation from attitude changes, while the effects of forward travel of the vehicle are corrected by a forward motion compensation (FMC) system. A system may provide FMC in any one of several ways, such as movement of the entire camera optical system, movement of a mirror sit-uated in front of the camera lens, or movement of the film relative to the lens system.
