Scanner for 3D Measuring the Teeth Contour
Goal was the development of a Mini-Projector and a record train to measure teeth contour, on the principle of “Moire”. Herby a raster of constants is being projected onto an object. A raster is also attached to the CCD-Sensor, which -with the correct alignment -creates an interference pattern. After signal processing, data is obtained from the 3D object. This 3D surface measurement technique is employed by clinics and allows them to non-intrusively measure teeth after grinding.
