Abstract:

Factors are discussed which affect photographic resolution as a function of format size for the same angular coverage on the ground. Static and flight tests were conducted with a 12-inch focal length K-17C camera, 6-inch focal length KA-30 camera, and a 3-inch focal length X-70-4 camera. The flight tests were conducted withALL THREE CAMERAS MOUNTED VERTICALLY IN A COMMON MOUNT INSTALLED IN A U. S. Navy F9F-8P aircraft. All three ca eras were exposed simultaneously. Two rate gyros provided camera roll and pitch rate information. The airborne resolution, both angular and linear is relate to the static resolution and a comparison of the performance of the three cameras is made for flights over high contrast resolution targets. Also presented for the three format sizes is information per frame, information per unit weight and information per unit volume of each camera. Author
