It uses an acoustic wave that when propagated through the lenses, creates a standing wave that changes the diffractive capabilities of the lens. It involves the properties of many materials to change the diffractive properties when subjected to acoustic waves. The acoustic waves are generally accomplished with a piezo electric transducer or modulator. The frequencies used are in the RF range, depending on the substrate. Substrates used include glass and silicon, as well as more esoteric transparent materials. The system described in the present invention involves the development of a lensing mechanism that comprises one or more acoustio-optic modulator(s), a transparent or semi-transparent substrate where the modulation is applied, and a non-parallel standing wave being propagated in the substrate. ## Claims ### Claim 1 A new lensing system mechanism comprising: a) One or more acousto-optic modulator(s) b) A transparent (or semi-transparent) substrate(s) where the modulation is applied c) A non-parallel standing wave being propagated in the substrate. ### Claim 2 (depends on 1) The system of claim 1 wherein the acousto-optic modulators are placed sequentially to produce a lensing pipeline. ### Claim 3 (depends on 2) The system of claim 2 wherein the lenses also have a traditional lens mixed in the pipeline. ### Claim 4 (depends on 2) The system of claim 2 wherein the pipeline also has a mirror. ### Claim 5 (depends on 2) The system of claim 2 wherein the pipeline inverts an image. ### Claim 6 (depends on 1) The system of claim 1 wherein the modulators create a concentric standing wave. ### Claim 7 (depends on 1) The system of claim 1 wherein the modulators creates a deformed wave that corrects for astigmatism. ### Claim 8 (depends on 1) The system of claim 1 wherein the lens/es create zoom, focus corrections. ### Claim 9 (depends on 1) The system of claim 1 wherein the lens/es adjust for angular stabilization. ### Claim 10 (depends on 1) The system of claim 1 wherein the system is enhanced with an eye tracker. ### Claim 11 (depends on 1) The system of claim 1 wherein the system is enhanced distance sensor. ### Claim 12 (depends on 1) The system of claim 1 wherein the lens/es have a reflective surface. ### Claim 13 (depends on 1) The system of claim 1 wherein the system is mounted directly over an imaging sensor or imager. ### Claim 14 (depends on 1) The system of claim 1 wherein the substrate(s) are flexible (contact lenses). ### Claim 15 (depends on 1) The system of claim 1 wherein the system is embedded into a flexible structure (contact lenses). ### Claim 16 (depends on 1) The system of claim 1 wherein the system comprises piezo transducer(s), wherein the piezo transducers are excited remotely through RF rather than direct wiring. ### Claim 17 (depends on 1) The system of claim 1 wherein the system is mounted on eyewear. ### Claim 18 (depends on 1) The system of claim 1 wherein the system is mounted on a helmet. ### Claim 19 (depends on 1) The system of claim 1 wherein the system is mounted on contact lenses. ### Claim 20 (depends on 1) The system of claim 1 wherein the system is mounted on a telescope or as part of a stage in a telescope. ### Claim 21 (depends on 1) The system of claim 1 wherein the excitation of the substrate is accomplished by an RF transducer rather than an acoustic transducer or using a magnetic transducer, in other words, phonons, polaritons or magnons can be used depending on the material excitation properties. ### Claim 22 (depends on 1) The system of claim 1 wherein the substrate is liquid. ### Claim 23 (depends on 1) The system of claim 1 where a temperature sensor is used to compensate for changes in the substrate. ### Claim 24 (depends on 1) The system of claim 1 where an imager is used to tune or provide control feedback to the lens. ### Claim 25 (depends on 1) The system of claim 1 where the lenses are used to automatically hide specs of dust or scratches deposited on the lens. ### Claim 26 (depends on 1) The system of claim 1 where a gyroscope is used to provide guidance to the controls system to provide optical image stabilization. ### Claim 27 (depends on 1) The system of claim 1 where an imager is added, and the lens is used to temporarily block high intensity events by redirecting the rays out of the area of the imager. ### Claim 28 (depends on 1) The system of claim 1 where the lens is used to create a simulated aperture by redirecting some of the rays out of the imager (or eye). ### Claim 29 (depends on 1) The system of claim 1 where the lens is used to redirect images to areas of the imager (or eye) that are functioning, this could be used for users with macular degeneration.
