An electro-optical controlled zooming/focusing lens system based on spatial light modulators that does not require any mechanical movement of the lenses is presented. The system can focus an object over a long range of distances. It also has the property of a conventional zoom lens that the effective focal length of the lens can be adjusted while the image plane is held fixed.
