Abstract
A test apparatus for electro-optical printed circuit boards having optical waveguides comprises a control device, a beamer and a camera, which can be positioned in such a way that light emitted by the beamer can be coupled by means of a first deflecting element to optical waveguides of the circuit board and can be coupled out by means of a second deflecting element into the field of vision of the camera. The beamer is used in a first phase to determine the position for each deflecting mirror of the first deflecting element which a light spot needs to assume in the image projected by the beamer so that the light spot illuminates the deflecting mirror. The beamer is used in a second phase to illuminate at least one deflecting mirror and to carry out the testing of the optical waveguide associated with the at least one deflecting mirror.
