Sub‐Nyquist interferometry: implementation and measurement capability

Optical Engineering, 1996
Sub-Nyquist interferometry (SNI) provides a method for measuring wavefronts with large departures from a reference sphere, such as those encountered when testing steep aspheric surfaces. SNI allows wavefronts with several hundred waves of departure to be recorded and analyzed.
