Abstract
An operational autofocus system, which directly senses deviations in back focal distance of the camera lens and restores the camera to a best-available focus, has been successfully employed in long focal length reconnaissance cameras. This microprocessor-based system entails the use of internal optical elements to dynamically measure and adjust the back focal length to continuously maintain a best focus position.
