Abstract
Optical Physics Company is proposing to implement an interferometric angle sensor for the purpose of determining the relative angle between the two diffracting crystals. Two approaches can be pursued, namely (1) the dual grating interferometer, and (2) the angle interferometer. The estimated cost of materials for building the angle sensor in quantity ranges between $2K and $12K. The expected accuracy is better than 0.1 arc seconds across a range of 0.25 degrees. The design meets all requirements named in the solicitation, including size, weight, bandwidth and lifetime. The Phase 1 work will build and test a prototype interferometer which will confirm the design and prepare for fabrication of a deliverable unit in Phase 2.
