High Resolution Aerial Photography

Earle B. Brown

At the close of World War II, attainable levels of resolution in aerial photography were of the order of 20 lines/mm. This level has been increased to better than 100 lines/mm, providing a ground resolution of 1 ft for an 18-in. focal-length camera operating at an altitude of 40,000 ft. This improvement permits better ground resolution, smaller, lighter cameras and higher operating altitudes. Four factors contributing to this growth are better films, improvements in lenses, more sophisticated camera systems and improvements in methods of analysis.
