Abstract: Systems and methods are providing for endoscopically visualizing tissue within a patient. In one aspect, an endoscope comprises an elongate shaft having a distal end and a proximal end and a visualization section at the distal end of the shaft. The visualization section includes a proximal surface and an outer surface spaced apart from the proximal surface. At least one of the proximal surface or the outer surface of the visualization section has an average surface roughness less than about 50 nanometers RMS. The endoscope allows improved remote visualization while not interfering with the autofocus feature of a video capture system and not causing increased light reflectance and glare due to improved surface finish.

Abstract: An endoscope includes a distal end portion in which an optical unit and a treatment instrument channel are held such that a photographing optical axis, a central axis of the distal end portion, and a central axis of the treatment instrument channel are linearly aligned When viewed from an end face of the distal end portion. The first magnet and the second magnet are arranged at non-rotationally-symmetric positions with respect to the photographing optical axis, and a region of the optical unit, which is on a side where a distance between the first magnet and the second magnet on an arc of a circle around the photographing optical axis is short, faces the treatment instrument channel.

Abstract: Calibrating an intraoral scanner includes obtaining reference data of a reference three-dimensional (3D) representation of a calibration object and obtaining, based on the intraoral scanner being used by a user to scan the 3D calibration object, and from one or more device to real-world coordinate transformations of two-dimensional (2D) images of the 3D calibration object, measurement data. Calibrating the intraoral scanner further includes aligning the measurement data to the reference data to obtain alignment data and updating, based on the alignment data, said one or more transformations.

Abstract: Endoscopes, multicore endoscope fibers and configuration and operation methods are provided. The fibers may have hundreds or thousands of cores and possibly incorporate working channel(s) and additional fibers. The fiber may be used at different optical configurations to capture images of tissue and objects at the distal tip and to enhance a wide range of optical characteristics of the images such as resolution, field of view, depth of field, wavelength ranges etc. Near-field imaging as well as far-field imaging may be implemented in the endoscopes and the respective optical features may be utilized to optimize imaging. Optical elements may be used at the distal fiber tip, or the distal fiber tip may be lens-less. Diagnostics and optical treatment feedback loops may be implemented and illumination may be adapted to yield full color images, depth estimation, enhanced field of views and/or depths of field, and additional diagnostic data.

Abstract: An endoscope includes in order from an object side, an objective optical system, an optical-path splitter, an image sensor, and an image processor. A λ/4 wavelength plate is disposed between the objective optical system and the splitter. The splitter includes first and second prisms, and has a beam splitting surface at which the first prism and the second prism are brought into close contact. The splitter splits light at the beam splitting surface, into a first optical path through which P-polarized light is transmitted and a second optical path through which S-polarized light is reflected. The first and second prisms are slid relative to one another along the beam splitting surface to adjust optical path lengths of the first and second optical paths, and are disposed at positions to cancel an amount of shift in focusing positions of extraordinary and ordinary light, and satisfy specific conditional expressions.

Abstract: A light source apparatus for an endoscope includes an optical fiber that guides emission light emitted from a light source and is incident on a fiber end face, a ferrule having a ferrule end face having a through-hole in which the optical fiber is inserted, a holder to which the ferrule is fixed, the holder having a reflecting surface that reflects first reflected light to thereby emit second reflected light, the first reflected light being the emission light reflected on the fiber end face, and an optical sensor that receives the second reflected light disposed between the light source and the fiber end face and in a region facing the reflecting surface through an optical axis.

Abstract: A system comprises alight source to provide light, an optical system comprises focusing optics to focus the light onto a focal surface, a detector to measure returning light that is reflected off of a three dimensional object, a translation mechanism to displace the focal surface along an imaging axis defined by the optical path, and one or more processor. The one or more processor is to generate measurement data comprising coordinates of a plurality of surface points of the three dimensional object based on the measured returning light; adjust the coordinates of the subset of the plurality of surface points along up to three axes to correct the measurement data so as to remove inaccuracies caused by changes in magnification at the focal surface; and generate a three dimensional model of the three dimensional object using corrected measurement data.
