To evaluate the relative importance of camera vibration in present-day survey photography, measurements were made of angular vibration of cameras in four aircraft with piston engines and in one with turboprops. Vibration components in roll, pitch, and yaw were determined by a somewhat modernized version of the open-shutter flashing-light technique. Image velocities due to vibration ranged from about 4 mm/s to about 10 mm/s with frequencies in the range 6 to 50 hertz. For comparison, image velocities due to forward motion of the aircraft in high altitude photography for mapping are 1.2 to 2.2 mm/s. It is apparent that image quality could be improved if camera vibration were reduced by better isolation of the camera from aircraft vibration, or by other measures. (Author)
