| 20080212078 | ARRANGEMENT AND METHOD FOR FOCUSING A MULTIPLANE IMAGE ACQUISITION ON A PROBER - The invention relates to a system and a method for capturing images in a prober. According to the invention, the surface of a test object is illuminated in succession with light of a first, second and third color; and an image capturing device records a gray scale image of the surface; and a composite image is produced from the three gray scale images by means of an image evaluating device. The object of the invention is to qualitatively improve the image capturing, in order to raise the positioning accuracy by means of an improved display, as a result of which, finely structured test objects can be used. This object of the invention is achieved in that the lighting device is designed as a unit, which can be controlled by the image evaluating unit and which produces at least three colors and which exhibits at least one light emitting diode (LED) as the lighting means. | 09-04-2008 |
