Abstract
A zoom lens is driven by an oscillating drive in continuous motion between different states of magnification to cause an image on a video screen to expand and collapse about the point on the optical axis of the lens. The expanding and collapsing image is viewed on the video screen and the location of the optical axis of the lens assembly is determined by identifying the point on the screen that does not move. The lens assembly is then adjusted so that the stationary point coincides with a reticle at the optical center of the image sensor.
