Title: Optical Figure Metrology for Deep Concave and Ogive Domes
Agency / Branch: DOD / NAVY
Contract: N68936-07-C-0045
Award Amount: $599,935.00


This is a Phase II proposal to develop an instrument for determining the optical figure of a new generation of infrared domes, such as tangent ogives, which are being developed to improve drag, range, speed, and payload capabilities of missiles. Since the optical tolerances achieved in the manufacture of missile domes have an important bearing on the performance capabilities of the systems that employ these domes, instrumentation and techniques for precision metrology are vital for quality assurance. The proposed work will demonstrate a technique for full aperture precision metrology of deep concave and ogive domes. The Phase I study produced instrument designs that incorporate an extremely robust, reliable, and accurate wavefront sensor for precision metrology of a transmitted wavefront, together with a projection system and data stitching procedure that cover the full aperture. The proposed wavefront sensor comprises a derivative of MetroLaser's widely used PhaseCam, a digital holographic interferometer, bringing the power and benefits of digital holography to meet the requirements set out in this solicitation. During Phase I, we employed an existing PhaseCam instrument backed up with a theoretical model to demonstrate the feasibility of the proposed instrument.
