Patent number: 11771317Abstract: Ocular surface interferometry devices, systems, and methods are disclosed for imaging an ocular tear film. An imaging device can be focused on the lipid layer of the tear film to capture optical wave interference interactions of specularly reflected light from the tear film combined with a background signal(s) in a first image, wherein the specularly reflected light may be produced from various portions of the ocular tear film by obliquely illuminating various portions of the ocular tear film with a multi-wavelength light source, such as in a tiling pattern(s). The imaging device can also be focused on the lipid layer to capture a second image containing the background signal(s) present in the first image. The second image can be subtracted from the first image to reduce and/or eliminate the background signal(s) in the first image to produce a resulting image, which can used to measure a tear film layer thickness.Type: GrantFiled: January 12, 2022Date of Patent: October 3, 2023Assignee: Tearscience, Inc.Inventors: Donald R. Korb, William L. Weber, Randal B. Chinnock, Benjamin T. Gravely, Stephen M. Grenon

Patent number: 11633091Abstract: An illuminator apparatus and method for illuminating an object field imaged by a rectangular image sensor having a first aspect ratio is disclosed. The apparatus includes an optical fiber having a proximal end disposed to receive a plurality of input light beams, each light beam having differing spectral properties, the optical fiber being operable to transmit the light beams along the fiber to a distal end of the optical fiber. The apparatus also includes an integrating element disposed to receive the light beams from the distal end of the fiber and combine the light beams to produce a generally homogenous illumination beam at a rectangular output face of the integrating element. The apparatus further includes an illumination projector operable to project an image of the output face of the integrating element into the object field to produce a generally rectangular illuminated region of the object field substantially corresponding to the portion of the object field imaged by the rectangular image sensor.Type: GrantFiled: July 2, 2021Date of Patent: April 25, 2023Assignee: Titan Medical Inc.Inventors: Randal B.
