Rapid and powerful method and apparatus for chromatic confocal three-dimensional measurement technology

摘要

Having a planar detector matrix disposed an array of multi-color point source, before the means for spectral separation of the horizontal direction and the objective lens for imaging and illumination of the object, object shape, especially human, especially It is a method and apparatus for chromatic confocal technique for the three-dimensional measurement quickly teeth in the jaw. According to the invention, for color calibration, the generated reference light beam spectrally defined using the components of an array of point light sources, in which the reference beam is detected for color separation in the horizontal direction through the reference path are combined in optical path within the vessel, and is focused as a reference point in the image on the detector matrix subsequently. The spectral position of the reference point is calculated in the detector matrix on the sub-matrices are defined by pixels high precision detector matrix on for spectral analysis of the object light by using the position, which then acquires the measured value and that it is used to, detector matrix can be blocked by the sub-matrix elongated completely, in which the planar array is arranged to be rotated by an acute angle to the spectral axis of the planar detector matrix on , when the point light source is projected to the plane of the detector matrix, the spectral axis plane connecting line of the point light source, the rotation around the optical axis of the apparatus (OA) that is to form an acute angle with the λ-axis takes place.
