  • Publication number: 20120022408
    Abstract: Embodiments of the invention are directed to improved surgical procedures such as ophthalmic procedures that utilize overlaid visual representations of three-dimensional data or other data with direct or indirect visual images of a surgical region (e.g. the eye) to provide improved information to a surgeon to speed surgical procedures and/or to provide improved outcomes of those procedures. In some embodiments, ophthalmic procedures are combined cataract removal and astigmatism reduction procedures. In other embodiments the ophthalmic procedures are corneal refractive surgical procedures that reshape the cornea to reduce astigmatism or other aberrations. In some ophthalmic procedures the three-dimensional data is topography data associated with the anterior surface of the cornea. In some embodiments, the three-dimensional data may be enhanced or replaced with aberrometric data associated with the optical path of the eye.

  • Publication number: 20120007839
    Abstract: Embodiments of the present disclosure provide augmented reality methods and systems where two or more component optical images are optically overlaid via the use of one or more beam splitters to become composite optical images wherein in some embodiments a second component optical image is an electronic optical image (an image from an electronically controlled emission source) while the first component optical image is one of a physical optical image (an image of a physical object from which diffuse reflection occurs), an electronic optical image, an emission optical image (an image from a non-electronic source that emits radiation), or a hybrid optical image (which composed of at least two of a physical optical image, and electronic optical image, or an emission optical image). In some embodiments the first and second component optical images are used to provide feedback concerning the quality of the overlaying and appropriate correction factors to improve the overlay quality.

  • Publication number: 20040057656
    Abstract: An optical communication system includes an input optical fiber, an output optical fiber, and first and second Risley prism pairs disposed in an optical path between the input optical fiber and the output optical fiber. A first actuator is configured to independently rotate a first and a second prism of the first Risley prism pair so that a first light beam is steered to be incident on the second Risley prism pair by adjusting the first Risley prism pair. A second actuator is configured to independently rotate a third and a fourth prism of the second Risley prism pair so that a second light beam is steered to be incident on the first Risley prism pair by adjusting the second Risley prism pair, providing optical beam alignment of the optical path for communication and optical switching.
