Abstract
A CCD camera ( ) images a work to generate its image data. An imaging optical system ( ) focuses an image of the work on the CCD camera ( ). A down-projection illumination source ( ) includes at least one semiconductor light-emitting device for producing a down-projection illumination light to illuminate the work from above. An illuminating optical system ( ) joins the illumination light from the down-projection illumination source ( ) to the imaging optical system in order to lead the illumination light to the work via the imaging optical system. These optical components are mounted on a chassis ( ) to construct an imaging probe ( ), which is employed at any angle as a measuring probe of a three-dimensional tester.
