摘要: An apparatus for focusing an image onto receptor is disclosed. The includes a stationary lens, rotatable frame that rigidly connected to the receptor, and base. base pivotally about rotational axis. focused by lens pivoting In alternate embodiment, voice coil actuator, servo loop driving electromechanical transducer measuring position of receptor. electrically loop. Connecting means connecting actuator are also provided. actuator. A method axis detecting information representative distance between object being imaged, in accordance with detected information.
