~Metrological Test Station for CCD Arrays~
Differntial measurement system for in-cryostat 9-CCD flatness measurement. Uses two Keyence absolute-distance laser triangulation sensors to compare the surface height of the surface under test (CCD array imaging surface) to an optical reference flat. Concept: Peter Takacs.
