Applied Research and Investigation of Components, Equipment and Systems of 70 mm Aerial Photography to Determine Performance Criteria for Reconnaissance Purposes

摘要

Under the authority of reference (a) Protype optics are tested and evaluated for resolution when it is considered that they may have a better performance capability than others of similar aperture and focal length.nSuch a lens, in order to qualify for aerial reconnaissance must possess a relatively high relative aperture in addition to a high resolution capability.
