Abstract
Traditional zoom lens designs employ multiple moving lens elements to provide simultaneous control of focal length and focal plane. We present an example of a simplified and compact zoom lens design by employing a single moving element to control only the focal length. In this zoom lens, wavefront coding is used to control the defocus. We describe the principles of operation with special attention to image processing. We simulate imaging and image restoration capabilities and present that the zoom lens provides high imaging quality.
