Publication number: 20190117063Abstract: Improved scanning ophthalmoscopes for scanning the retina of an eye are discussed in the present disclosure. One example scanning ophthalmoscope includes an uncollimated light source, a first scanning element, a second scanning element, a slit of a first aspherical mirror, and a second aspherical mirror. The uncollimated light source produces a beam of light to illuminate the retina. The beam of light is relayed from the first scanning element onto the second scanning element by the slit of the first aspherical mirror. The second aspherical mirror relays the beam of light from the second scanning element to the pupil of the eye.Type: ApplicationFiled: December 13, 2018Publication date: April 25, 2019Inventors: Yue QIU, Matthew EVERETT, Jochen STRAUB

Patent number: 8783868Abstract: Various approaches are disclosed for simultaneously generating optical coherence tomography (OCT) and confocal scanning laser images by spatially separating the signal normally used for OCT imaging with selective reflecting or beam directing devices. In one preferred embodiment, the invention includes a mirror having a central transmission region, such that the radially outer region of the returning signal beam is reflected and used for generating a confocal image while the central part of the signal beam is transmitted and used to generate an OCT image. In other embodiments, the signals may be spatially separated in other ways, such as with an optic having a reflective center surface, a mirror having two parts oriented at different angles, one or more wedged optics, or a dispersive component. A further aspect of the invention is the ability to increase the frame rate of the confocal imaging.Type: GrantFiled: December 21, 2012Date of Patent: July 22, 2014Assignee: Carl Zeiss Meditec, Inc.Inventors: Yue Qiu, Hueyming Tzeng

Patent number: 8049873Abstract: A surgical microscopy system is provided wherein an optical coherence tomography facility is integrated into a microscopy system. A beam of measuring light formed by collimating optics of an OCT system is deflected by a beam scanner, traverses imaging optics, and is reflected by a reflector such that the beam of measuring light traverses an objective lens of microscopy optics and is directed to an object region of the microscopy optics. A position of the beam of measuring light being incident on the reflector is substantially independent on a direction into which the beam of measuring light is deflected by the beam scanner. When traveling through the beam scanner, the beam of measuring light is comprised of a bundle of substantially parallel light rays.Type: GrantFiled: March 18, 2009Date of Patent: November 1, 2011Assignee: Carl Zeiss Meditec AGInventors: Christoph Hauger, Markus Seesselberg, Keith O'Hara, Yue Qiu, Xing Wei, Jochen M.

Publication number: 20030149570Abstract: An arrangement is provided for generating early warning of threshold violations in e-service management systems. The behavior of a variable is modeled statistically based on a plurality of data values of a variable collected over a period of time. The modeling generates a behavior model for the variable, represented by a set of model parameters. An early warning for a threshold violation of the variable with respect to a threshold is generated based on the behavior model and a plurality of data values of the variable collected online. The abnormal behavior of the variable is detected or forecasted according to online data values of the variable and the early warning generated.Type: ApplicationFiled: July 5, 2001Publication date: August 7, 2003Applicant: PANACYA, INC.Inventor: Shi-Yue Qiu
