Patent number: 11368670Abstract: A multi-layer viewing system includes a stationary imager and a beam projector to project physical layer markings onto a region of an object. A headset includes an augmented reality display that is sufficiently transparent to enable a user who is wearing the headset to directly view the object through the display, and to display annotation that is superimposed on the object. A processor is configured to receive a selected location relative to the target for display of the annotation, determine an orientation of the augmented reality display by identifying images of markings in acquired images or markings on the object, calculate a display location for displaying the annotation on the augmented reality display such that the annotation is perceivable by the user as displayed at the selected position, and display the annotation at the calculated display location.Type: GrantFiled: October 25, 2018Date of Patent: June 21, 2022Assignee: YEDA RESEARCH AND DEVELOPMENT CO. LTD.Inventors: Shimon Ullman, Daniel Harari, Liav Assif, Igal Koifman

Patent number: 9017316Abstract: A system and method of estimating a distance between the distal end of an optical fiber and treated tissue, to improve treatment efficiency, is provided herein. The estimation is achieved by modulating the numerical aperture of a light beam transmitted through the fiber to receive reflections from the tissue and distinguish them from other reflections in the fiber, and further by calculating the distance by comparing reflection intensities of beams having different numerical aperture values that illuminate the tissue over a very short period, so that tissue and environment conditions do not change much. Distance estimation may be carried out by modulating the treatment beam itself, or by a light beam transmitted between pulses of a pulsed treatment beam.Type: GrantFiled: July 25, 2011Date of Patent: April 28, 2015Assignee: Lumenis Ltd.Inventors: Arkady Khatchaturov, Uri Voitsechov, Igal Koifman
