Abstract
The invention is directed to an optical image recording arrangement of a three-dimensional object wherein an illuminating raster generator simultaneously generates a plurality of separate light spots in a first focal plane. The light spots in the first focal plane are imaged by optical elements into a second focal plane on the three-dimensional object. The image of the light spots is imaged by optical elements onto a first detector device having several detector elements. A displacing device is mounted in the beam path of the illuminating raster generator. The displacing device effects at least a two-axis position change of the first focal plane. The method of the invention determines the sharply imaged regions of a three-dimensional object in an optical image recording arrangement. An illuminating raster generator in the image recording arrangement simultaneously generates a plurality of separate light spots in a first focal plane. The light spots in the first focal plane are imaged by optical elements into a second focal plane on the three-dimensional object. The image of the light spots is imaged by optical elements onto a first detector device having several detector elements a…
