Metrology for Optically Precise Conformal Sensor Window
To meet the need of the Navy in fabrication and measurement of conformal windows, such as toroidal made of spinel, to precise optical tolerances, Applied Science Innovations (ASI) proposes Phase II development of the Interferometric Tomography metrology system, building directly on the Phase I success. The proposed metrology tool is a modular attachment for integrating a standard commercial interferometer with an existing optical fabrication tool. The new design will enable measurement of surface shapes of very large and heavy conformal aspheric windows, in a common fabrication process to ensure that the window is finished to specification. Phase I focused on the design, implementation, and tests of the proposed improved metrology, and on application-specific processing algorithms. In Phase II, the tool will be integrated into a metrology system for measurement of conformal freeform windows 30 x 30 cm and larger, to reach 50 x 50 cm and larger in Phase III.
