Test and alignment system for electronic display devices

A system for testing and aligning a CRT assembly comprising:

• a video pattern generator to be connected to said CRT assembly for generating an image of a video pattern on said CRT assembly;
• a plurality of optical sensor devices with independent fields of view, said optical sensor devices being mounted on a test fixture for sensing and producing image signals corresponding to separate details of said image of said video pattern on said CRT assembly, each of said optical sensor devices including a CCD camera head;
• camera head controllers each having a digital multiplexer to route digital information from the CCD camera heads to a video input channel processor;
• a computer including said video input channel processor to process said digital information, said computer executing a CRT assembly testing and alignment procedure;
• and
• a graphical user interface for guiding an operator performing adjustments on said CRT assembly through said CRT assembly testing and alignment procedure;
• wherein said test fixture includes a plurality of vertically spaced, generally horizontal supports supporting said CCD camera heads, each of said CCD camera heads including an associated drive actuable in response to an associated camera head controller to move laterally said CCD camera head along said respective support thereby to allow each of said CCD camera heads to be individually positioned with respect to said CRT assembly under inspection.
