Computerized fringe analysis allows interferometry to be quantitative rather than qualitative. The software available today allows the surface of an optic, or a complete optical system's wavefront, to be mapped in three dimensions. Not being limited to the mere handful of data points typical of other test methods, digital interferometry maps the item under test with hundreds, or even thousands, of data points to get a more complete picture of the surface or wavefront quality.
