Balanced, Periodic Error Free, Three Degree of Freedom Interferometer
Technology SummaryThis interferometric technology is able to measure tip/tilt and global displacement of a small target mirror (a few mm^2) using only one optical beam. Other interferometric systems require a much larger footprint on the target to measure a single axis of displacement. This means that to measure displacement, tip, and tilt, three identical...
