Publication number: 20230316554Abstract: Systems and apparatus for phase calibration in time-of-flight cameras. In particular, systems and methods are presented for a miniaturized cover design that at least partially encloses the time-of-flight (ToF) module. The geometry of the miniaturized design causes the signals reflected from the calibration device back to the ToF imager to have essentially the same time-of-flight. The design of the calibration device prevents the modulated emissions from leaking out to the environment.Type: ApplicationFiled: March 22, 2023Publication date: October 5, 2023Inventors: Tzu-Yu WU, Charles MATHY

Patent number: 10859438Abstract: A spectrally encoded endoscopy optical device includes a bundle of multi-mode optical fibers that transmits light received from an imaging target to a spectrometer. A far field pattern of light transmitted through a fundamental mode of at least one of the multi-mode optical fibers is nonparallel to an optical axis of the spectrometer for reducing nonuniformity of the far field pattern at an input sensor of the spectrometer. For still further reduction of such nonuniformity, a far field pattern of light transmitted through a fundamental mode of the bundle of multi-mode optical fibers is nonparallel to an optical axis of the spectrometer.Type: GrantFiled: January 23, 2020Date of Patent: December 8, 2020Assignee: Canon U.S.A., Inc.Inventors: Mitsuhiro Ikuta, Tzu-Yu Wu

Patent number: 10825152Abstract: Methods, apparatuses, systems, and storage mediums for correcting distortion of a spectrally encoded endoscopy (SEE) image are provided. A first reference pattern comprising a plurality of radial lines is scanned with an SEE spectral line to obtain a first image. Signs of a tangential shift and/or of a radial shift of the spectral line may be determined, and magnitudes of the tangential shift and of the radial shift may be computed. A second reference pattern comprising at least a circle with the SEE spectral line may be scanned to obtain a second image in a case where the radial shift is positive. The magnitude of the radial shift may be computed based on the magnitude of the tangential shift and a radius of the circle. The tangential shift and the radial shift may then be applied for correcting distortion.Type: GrantFiled: September 7, 2018Date of Patent: November 3, 2020Assignee: Canon U.S.A., Inc.Inventors: Tzu-Yu Wu, Bin Wu

Patent number: 10806329Abstract: Some embodiments of a device comprise a sheath, a first light-guiding component, a second light-guiding component, an optical-focusing component, and an optical-correction component. The second light-guiding component and the optical-focusing component are aligned on an optical axis.

Patent number: 10791923Abstract: An optical probe includes first and second light guiding components, and a ball lens arranged along an optical axis and enclosed in a sheath having asymmetric optical power. The probe transmits at least two light beams including first and second beams each having a different wavelength. The ball lens has a curved surface and an angled surface arranged such that light is reflected off from the angled surface and focused by the curved surface at a working distance with a beam waist profile having lateral and longitudinal directions. Beam waist locations of the first and second beams are different from each other, and the beam waist profiles of the first and second beams in the lateral direction differs less than the beam waist profiles in the longitudinal direction. This ball lens design compensates for the sheath asymmetric optical power and provides balanced astigmatism and substantially achromatic performance.Type: GrantFiled: September 20, 2019Date of Patent: October 6, 2020Assignee: Canon U.S.A., Inc.Inventor: Tzu-Yu Wu
