  • Patent number: 11709324
    Abstract: An optical connection includes a plurality of ferrules, an optical contact to allow transfer of light, a mechanical contact to allow torque transfer from the optical connection, and a rotational self-alignment structure to allow optical fibers of different optical connectors to self-rotate into rotational self-alignment upon action of connecting, wherein the ferrules are aligned and engage the torque transfer. The rotational self-alignment structure can be a tooth configuration, a helical thread configuration, a ferrule guide configuration, a spring sleeve configuration, derivatives thereof and combinations therefrom.

  • Patent number: 11497382
    Abstract: A system and method for displaying an endoscope image in a preferred orientation. An endoscope scans a sample with spectrally encoded light by rotating imaging optics inside an endoscope guide. A processor generates an image based on light returned from the sample, and rotates the image by a first angle offset value and a second angle offset value to display the rotated image in the preferred orientation. The first offset value is an angle difference between a specific direction in which the image is to be displayed on a display and a direction in which the tip of the endoscope is oriented with respect to the imaging plane. The second offset value is an angle difference between a direction of the line of scanning light projected onto a plane perpendicular to the tip and the specific direction in which the image is to be displayed.

  • Patent number: 11259694
    Abstract: Endoscope window assembly designs and methods of assembling sub-millimeter imaging endoscopes are disclosed. An endoscope apparatus comprises an elongated cylindrical probe having rotating illumination optics in the middle and at least one detection fiber and a spectrometer connected to the detection fiber and a light source connected to the illumination optics and a processor for imaging. An optically transparent window is attached to the cylindrical probe at the distal end thereof, the window seals the rotating illumination optics inside the cylindrical probe, and the at least one detection fiber is located on the outer surface of the cylindrical probe. The present disclosure provides various embodiments of a window component that covers only the illumination component of the optical probe.

  • Patent number: 11213191
    Abstract: An endoscopic probe extending from a proximal end to a distal end thereof, and configured to be inserted in a tubular lumen to observe a sample is disclosed. The probe includes a first waveguide enclosed within an inner sheath and extending from the proximal end to the distal end along an axis of the inner sheath; and a plurality of second waveguides having at least the distal ends thereof arranged in one or more rings around the inner sheath to surround the distal end of the first waveguide. At the distal end, the axis of each of the second waveguides is tilted with respect to the axis of the first waveguide by a tilt angle which can be adjustable. This novel endoscopic probe has a resultant numerical aperture larger than the numerical aperture of each of the second waveguides, and it may be applicable to forward-viewing spectrally encoded endoscopes (SEE).

  • Patent number: 10794732
    Abstract: An image processing apparatus and method for detecting a position of a rotating optical fiber is provided. The apparatus includes at least one rotating optical fiber that rotates about an axis of rotation and that emits light towards a surface and at least two stationary fibers for transmitting light reflected from a surface, each of the at least two stationary fibers having a known predetermined position relative to each other and to the axis of rotation of the at least one rotating optical fiber. At least one detector is configured to detect an intensity of light transmitted through each of the at least two stationary fibers within a given time interval and at least one calculator is configured to use the detected intensities and the known predetermined positions of each of the at least two stationary fibers to determine a relative angular position of the rotating optical fiber with respect to the at least two stationary fibers.
