  • Publication number: 20240341596
    Abstract: A method for creating a composite image of at least part of an eye is disclosed. The method includes receiving a first image of the eye captured along a first axis, receiving a second image of the eye captured along a second axis that is offset from the first axis, and receiving a third image of the eye captured along a third axis that is offset from the first axis and the second axis. The method then includes combining at least part of the first image, at least part of the second image, and at least part of the third image to create a composite image of at least part of the eye, the composite image having a field of view that is at least 180 degrees.

  • Patent number: 9423357
    Abstract: One embodiment relates to an oblique illuminator. The oblique illuminator includes a light source emitting a light beam, a first reflective surface, and a second reflective surface. The first reflective surface has a convex cylindrical shape with a projected parabolic profile along the non-powered direction which is configured to reflect the light beam from the light source and which defines a focal line. The second reflective surface has a concave cylindrical shape with a projected elliptical profile which is configured to reflect the light beam from the first reflective surface and which defines first and second focal lines. The focal line of the first reflective surface is coincident with the first focal line of the second reflective surface. The first and second focal lines of the second reflective surface may be a same line in which case the elliptical curvature is a projected spherical profile. Other embodiments, aspects and features are also disclosed.

  • Patent number: 7654715
    Abstract: A system for illuminating a specimen are disclosed herein. In general, the system may include an illumination source configured to generate light with an uneven distribution at a pupil plane and field stop of the system, a lightpipe coupled for redistributing the light across the pupil plane and field stop, and at least one optical element configured to direct the redistributed light onto a specimen. The lightpipe may generally include a cone-shaped portion and a rectangular-shaped portion. The cone-shaped portion is configured for modifying an angular distribution of the generated light, so that the redistributed light is uniformly distributed across the pupil plane of the system. The rectangular-shaped portion is formed contiguous with the cone-shaped portion and configured for modifying a spatial distribution of the generated light, so that the redistributed light is uniformly distributed across a field stop of the system.

  • Patent number: 7313246
    Abstract: Eyewear comprises a microphone and a speaker. An eyewear neck strap couples the microphone and speaker to a wearer unit carried by the eyewear wearer. The wearer unit exchanges wireless signals with a base station. The base station is coupled to various devices such as surgical theater equipment, and/or to a telecommunication system, such as a telephone system. The eyewear enables the wearer to conduct hands-free communication such as telephone conversations and command and control operations, as well as to perform other hands-free tasks such as dictation. The wearer also receives data in audio form or as an image using a video display coupled with the eyewear.
