A variable spacing diffraction grating is fabricated using micro-electromechanical (MEMS) technology. An array of interconnected beam elements is fabricated into a diffraction grating and mounted in such a manner that one or both ends of the array of beam elements may be actuated using a mechanical actuator. The beam elements may be linear, spiral shaped or arranged in a staircase structure. Applying a force to one or both ends of the array of beam elements changes the spacing of the grating, and presents a different ruling spacing distribution to incoming radiation, thus altering the diffracted angle among individual diffraction orders of the wavelength. Controlling the diffracted signal in this way allows for specific diffraction pass bands to be fixed on a particular detector or a particular area of a detector or optical relay lens or lenses.
Tuned Fresnel Lens For Multifocal Intraocular Applications Including Small Incision Surgeries
Vision correcting lenses utilizing the principles of both Fresnel lenses and Fresnel zone plates are disclosed. The lenses of the present invention provide multifocal vision correction, and are most preferably used to provide intraocular lenses for small incision surgeries. Using the concept of a "tuned" Fresnel lens, intraocular and other types of vision correcting lenses are provided by the present invention which overcome the limitations found in typical Fresnel lenses by phase synchronizing the light passing through the lens. As disclosed, the groove width and depth of the lens may be varied to provide the synchronization, and also to provide multifocal vision. Also, the design of the present invention permits a relatively thin lens to be designed, therefore making it particularly applicable to small incision surgeries since it may be rolled or folded into a configuration which is easily inserted into an incision in the eye.
Multifocal lenses for improving vision are disclosed. The lenses of the present invention use at least one diffractive zone located in a defined portion of the surface of a refractive lens to achieve highly efficient multifocal vision by providing nearly 100% efficiency in the +1 diffractive order. The lenses disclosed may be used for both contact lenses and intraocular lens as well as other vision correcting applications.
