Abstract: A method for generating a 3D image includes driving structured light projector(s) to project a pattern of light on an intraoral 3D surface, and driving camera(s) to capture images, each image including at least a portion of the projected pattern, each one of the camera(s) comprising an array of pixels. A processor compares a series of images captured by each camera and determines which of the portions of the projected pattern can be tracked across the images. The processor constructs a three-dimensional model of the intraoral three-dimensional surface based at least in part on the comparison of the series of images. Other embodiments are also described.

Abstract: A thermal defogging system and method for an optical instrument is described. In one embodiment, the thermal defogging system for an optical instrument is comprised of: at least a primary housing, the primary housing defining an aperture for transmission of optical signals, a transparent element adapted to be aligned with the aperture for transmission of optical signals, at least one side of the transparent element facing the external environment; and a transparent conductive layer covering an area at least as large as the optical footprint of the transmitted optical signal through the transparent element, wherein responsive to the application of electrical power to the transparent conductive layer, the transparent conductive layer generates heat that is thermally communicated to the least one side of the transparent element facing the external environment.

Abstract: Removable barrier devices (e.g., sleeves) for covering medical scanning devices to reduce the chance of cross-contamination between patients and/or to protect the scanning devices from physical damage. The barrier device can include a cover that has an integrated window for passing optical signals between the scanning device and an external environment. The cover can include a sleeve that covers a handle portion of the scanning device to prevent contamination of the handle from a user's hand or glove. The cover and sleeve may both be formed of the same flexible material, or the cover may be rigid to maintain the window in a fixed position and the sleeve may be flexible to allow a user to activate a button or touchpad on the handle. An interface region between the cover and sleeve may provide a hermetic seal. The window may include a nano structured antireflective material to limit internal reflections.

Abstract: Apparatuses, including sleeves, intraoral scanning systems to use these sleeves, and methods of using the sleeve, that authenticate the sleeve for use with an intraoral scanning system. Authentication may include verifying that the sleeve is new (unused) and/or verifying that the sleeve is appropriate and/or intended for use with the intraoral scanning system. Once authenticated, operation parameters of the intraoral scanning system can be automatically set based on information from a scanned identifier on the sleeve.

Abstract: An apparatus for intraoral scanning includes an elongate handheld wand that has a probe. One or more light projectors and two or more cameras are disposed within the probe. The light projectors each has a pattern generating optical element, which may use diffraction or refraction to form a light pattern. Each camera may be configured to focus between 1 mm and 30 mm from a lens that is farthest from the camera sensor. Other applications are also described.

Abstract: Abstract An intraoral scanning system comprising: an elongate handheld wand with a probe at a distal end; a structured light projector configured to project a uniform structured light pattern onto an object, the structured light projector comprising a light source configured to transmit light and a pattern generating optical element configured to generate the uniform structured light pattern when the light is transmitted from the light source and through the pattern generating optical element; a plurality of cameras configured to capture points of the uniform structured light pattern projected onto the object by the structured light projector; and one or more processors configured to: determine a correspondence between projected points in the uniform structured light pattern generated by the structured light projector and captured points of the uniform structured light pattern captured by the plurality of cameras viewing the uniform structured light pattern projected onto the object; and use triangulation and the determined correspondence to determine three-dimensional points in space associated with the captured points of the uniform structured light pattern captured by the plurality of cameras viewing the uniform structured light pattern projected onto the object
