A camera that takes photographs from horizon to horizon. This type of camera is extensively used in low-level high-speed photography. Some designs utilize a lens that revolves about an axis perpendicular to the optical axis; in other designs, the camera itself is swung from side to side to obtain a panoramic field of view. The film moves like a conveyor belt at a speed synchronized with the speed of the moving image, so as to ensure congruency between the image and the film. The two main types of panoramic cameras are the direct-scanning rotary lens and the rotary prism. The camera may be mounted vertically or obliquely within the aircraft to scan across or along the line of flight.
