A system and method for performing long range, non-linear, sector scan panoramic electro-optical reconnaissance of a scene from an airborne craft. According to the present invention, the reconnaissance can be performed at increased aircraft velocities with a given detector technology at a desired level of performance. The system according to the present inventio n comprises a focal plane array that is configured to detect an image of the scene, and to convert the image into electronic charge information representing the image, a main electronics unit that converts the electronic charge representation into an electronic signal which is a digital representation o f the image. A lens arrangement is used to focus a narrow slit of the scene onto t he focal plane array, and a rotating prism scans the slit across the scene at a non- linear scanning velocity as determined according no the present invention. T he electronic signal is transmitted to a ground station where it is processed t o provide visual image data and that represents the scene, distortion induced into this data as a result of the non-linear scan velocity is removed to provide a distortion free final image.
