摘要: 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.

摘要: In one aspect of the present disclosure, improved end optics are disclosed that maximize the numerical aperture focused at a sample point while minimizing unwanted artifacts such as vignetting. The configurations also maintain centering of the excitation/collection beam on the objective if the probe tilts or bends. The disclosed configurations are particularly suited to probes wherein the excitation and/or collection paths between the probe and the laser/analyzer are coupled through multimode fibers, such as in Raman and other forms of laser spectroscopy. The disclosure includes the insertion of one or more additional lenses between the probe head and the focusing objective at the probe tip.

摘要: An illumination system is provided that includes a spatial fiber arrangement with an optical element at the distal end of the fiber arrangement. The fiber arrangement has a first region including individual fibers with a significantly smaller active diameter in comparison with the individual fibers of a remaining region. The optical element at the distal end is assigned the remaining region. The fiber arrangement can be a rigid fiber rod that includes an intermediate region provided between the first region and the remaining region. The intermediate region suppresses stray light transfers between the first and remaining regions. The fiber arrangement can include an optical coupling element at a proximal end of the fiber rod.

摘要: An image quality is improved although a medical stereomicroscope optical system and a medical observation apparatus are small and light. An objective optical system and a plurality of imaging optical systems are arranged in an order from an object side to an image side, and the imaging optical system has at least a single aspheric surface. Accordingly, a spherical aberration and a field curvature are improved, and the image quality is improved although the medical stereomicroscope optical system and a medical observation apparatus are small and light.

摘要: A computing device comprises a processor that uses a field curvature model that is calibrated to a confocal imaging apparatus. The processor receives intensity measurements generated by pixels of a detector of the confocal imaging apparatus. The processor determines, for each pixel, a focusing setting of the confocal imaging apparatus that provides a maximum measured intensity. The processor determines, for each pixel, a depth of a point of a 3D object associated with the pixel that corresponds to the determined focusing setting. The processor adjusts the depth of at least one point of the 3D object based on applying the determined focusing setting for the pixel associated with the at least one point to the field curvature model to compensate for a non-flat focal surface of the confocal imaging apparatus. The processor determines a shape of the 3D object based at least in part on the adjusted depth.

摘要: Techniques, systems, and devices are disclosed for obtaining optical images of a targeted object or scene such as a person's organ or tissue based on a fiber bundle having imaging optical fibers and optical phase modulation for improved imaging quality without using an objective lens to receive light from a target. Among its applications is an endoscope that bears no lens at the distal end, which affords miniaturization and bendability, and that has adjustable focal distance.

摘要: Valve gap measuring device for measuring an axial gap between a valve seat ring of an internal combustion engine which is pressed into a blind through bore, and the base of the blind through bore, has an imaging optical system for imaging the gap at at least one circumferential location on the borehole. The imaging optical system is in image transmission connection with a digital image sensor and a digital evaluation apparatus situated downstream from the image sensor. The evaluation apparatus is configured for determining the gap width, based on the image recorded by the image sensor.
