Interferometers Characterization
Procedure and characterization result for two vibration insensitive phase shifting interferometers will be presented. Typical applications of the vibration insensitive interferometers include the testing of large astronomical primary mirrors with long radii of curvature in a severe vibration environment. The procedure list the steps for characterizing the two interferometers. The characterization compares the two interferometers and compares to its own specification.
