Abstract:
1. A measuring arrangement for the three-dimensional measuring of at least part of an object ( 28 ), in particular a semi-transparent object, comprising one light source ( 10 ) with a continuous spectrum, one device ( 14 ) for generating a multi-focal illumination pattern ( 16 ), one objective lens ( 18 ) with high chromatic aberration to image foci of the illumination pattern onto the object, one detector unit ( 40 ) for determining the wavelength spectra of the foci imaged confocally onto the object by the objective lens, as well as one spectrum-dispersing device ( 34 , 36 , 38 ) that is arranged between the confocally imaged foci and the detector device, wherein in the plane of the confocally imaged foci is arranged one first matrix of holes ( 30 ) with first holes ( 32 ), whereby the geometric arrangement of the first holes corresponds to the geometric arrangement of the foci of the multi-focal illumination pattern.
