Abstract: A variable focal length optical assembly may include a deformable entry lens element, a deformable first reflective element and a deformable second reflective element. Using a controller coupled to the deformable elements, an external force such as a mechanical, electrical, electromechanical, or electromagnetic force is applied to the deformable elements to provide any number of different focal lengths. Since the deformation of the deformable elements, and consequently the changes in focal length, occur much faster than the playback frame rate, a number of sub-frames, each containing an image obtained at a different focal length, are associated with each playback frame. The availability of multiple images in the form of sub-frames permits the selection of an optimal image for inclusion in the final playback frame sequence. The availability of multiple images in the form of sub-frames at different focal lengths also permits the seamless incorporation of zoom-in and zoom-out effects.

Abstract: A beam expander dynamically changes focal lengths of optical elements to effect a dynamic change in magnification. Dynamically changing magnification allows the beam expander to dynamically vary a lateral dimension of an output beam. One or more deformable optical elements are controlled to adjust focal length, for example synchronously changing a respective focal length of a first and a second set of optics ( e.g ., deformable reflector, lenses) such that a sum of the focal lengths remains constant. Such allows fast variation of the lateral dimension of the output beam. The deformable optical elements may deform subject to applied electromagnetic energy, an electrical potential or magnetic field, facilitating fast response.
