    Abstract: A high numerical aperture opto-mechanical scanner for writing refractive index modifications includes a fast axis scanner having a fast scanning axis. A waveform generator is electrically coupled to the fast axis scanner, and a waveform is provided by the waveform generator which defines a fast scan of the fast axis scanner. A scanning lens assembly is mechanically coupled to the fast axis scanner, the scanning lens assembly having a NA greater than 0.5 and a scanning lens motion along the fast scanning axis. A femtosecond laser is optically coupled through the scanning lens assembly to a surface of a material, creating a femtosecond laser light scanning pattern to write the refractive index modifications into the material. A method for writing refractive index modifications using a high numerical aperture opto-mechanical scanner is also described.

  • Publication number: 20190230332
    Abstract: The present disclosure is generally related to capturing a scene and projecting a virtual window to one or more observers. A virtual window may mimic the experience a viewer has when looking through a real window. In some embodiments, for a single observer looking at a digital display or digital screen, a head-tracking camera on the same side of the screen as the observer can determine the position of the observer relative to the screen. The camera may be a 3D camera, stereoscopic camera, a wide angle lens camera, or an array of cameras (e.g., two or more). A camera on the other side of the screen can then image the view on the other side observer is relative to the window of the screen and software can determine the correct portion of the view that should be displayed on the screen to the observer.

  • Publication number: 20190192174
    Abstract: A distal biceps tendon repair device is disclosed. The device allows for anatomically correct biceps tendon repair using a single incision anterior approach without the risk associated with a double incision posterior approach. The distal biceps tendon repair device eliminates the necessity of cutting supinator muscle and greatly reduces the risk of contact or damage to vital structures such as arteries or nerves. The device has a bone drill guide mechanically coupled to a cannulated bone hook. A retrieval wire passes through the cannulated bone hook to grasp a suture or suture guide that has passed through a cannulated drill bit retained by the bone drill guide, the retrieval wore brings the suture through the cannulated hone hook, thus bringing the suture through and around the hone for subsequent anatomically correct attachment and placement of sutures used to reattach the distal biceps tendon to the bone.

  • Publication number: 20190167094
    Abstract: A method for imaging vertebrate translucent retinal structures includes imaging a translucent retinal structure at a first imaging plane in the retina with a light source focused at such first imaging plane, and detecting reflected light with a non-confocal off-axis detector, wherein the detector is axially displaced from a plane conjugate to the first imaging plane to a plane conjugate to a reflective layer deeper in the retina along a path of illumination from the light source. The method may employ scanning ophthalmic instruments, and enables an enhancement in contrast and collected intensity by axially displacing the image detector away from the object of interest to positions closer to conjugate to layers of strong retinal reflection, like the photoreceptors or the interface between the choroid and the sclera, that act as a diffusive screen.

  • Publication number: 20190141315
    Abstract: A system for displaying one or more images in three dimensions. The system has a three dimensional illumination volume containing a gas that emits one or more types of visible light when at certain multi-photon excited states. The system includes lasers (e.g. lasers with beams outside of the visible wavelengths) that can be directed to intersect in the illumination volume to excite particles of the gas to a multi-photon excited state to emit visible light. Scanning the beam intersection (or multiple beam intersections) through the illumination volume generates three dimensional images.

  • Patent number: 10271991
    Abstract: A method for providing vision correction to a patient. The method includes: (a) measuring the degree of vision correction needed by the patient and determining the location and shape of refractive structures that need to be positioned within the cornea to partially correct a patient's vision; (b) directing and focusing femtosecond laser pulses in the blue spectral region within the cornea at an intensity high enough to change the refractive index of the cornea within a focal region, but not high enough to damage the cornea or to affect cornea tissue outside of the focal region; and (c) scanning the laser pulses across a volume of the cornea or the lens to provide the focal region with refractive structures in the cornea or the lens. Again, the refractive structures are characterized by a change in refractive index, and exhibit little or no scattering loss.
