Optimum Focusing of Space Camera Systems
After the success of the Ranger 7 television mission, an exhaustive study was undertaken to determine whether the performance of the succeeding Ranger payloads could be made to surpass that of Ranger 7. In this paper, (1) the effect of thermal-vacuum environment on camera focus is found to be substantial and a method of compensation for this effect is discussed; (2) the focusing methods used on Ranger 7 are evaluated; and (3) the improvements in focusing based on (1) and (2) above are discussed.
