~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.
