Abstract: A device, method and system for utilizing an optical array generator, confocal measurement/depth of focus techniques to generate dynamic patterns in a camera for projection onto the surface of an object for three-dimensional (3D) measurement. Projected light patterns are used to generate optical features on the surface of an object to be measured and optical 3D measuring methods which operate according to triangulation, confocal and depth of focus principles are used to measure the object.

Abstract: A device and method and system for utilizing confocal measurement and an optical arrangement to produce 3D color images. A color measurement optical path and a 3D measurement optical path may coincide at least at an object side of the device, and a minimal amount of light is extracted from a monitoring beam for color measurement without affecting 3D measurement.

Abstract: A device, method and system for utilizing an optical array generator to generate dynamic patterns in a dental camera for projection onto the surface of an object, while reducing noise and increasing data density for three-dimensional (3D) measurement. Projected light patterns are used to generate optical features on the surface of the object to be measured and optical 3D measuring methods which operate according to triangulation principles are used to measure the object.
