More Information
Summary:An apparatus for intraoral scanning comprises an elongate handheld wand comprising a probe at a distal end, one or more light projectors, and two or more cameras. Each light projector comprises at least one light source configured to generate light and a pattern generating optical element configured to generate a pattern of light when the light is transmitted through the pattern generating optical element. Each camera comprises a camera sensor and one or more lenses and is configured to capture a plurality of images that depict at least a portion of the projected pattern of light on an intraoral surface, wherein each camera is configured to focus at an object focal plane that is located between about 1 mm and about 30 mm from a lens of the one or more lenses that is farthest from the camera sensor.
