Title: Interferometric measurement of geometry and image quality of non-spherical surfaces - using two-beam interferometer with adjustable phase between measurement and reference paths
Inventor: HARNISCH WOLFGANG
IPC: G01M11/02
Filed: 1991-06-04
Abstract: Interferometric measurement of the geometry and imaging quality of a non-spherical optical element or system (8) involves placing it in the aperture matched test beam path of a two-beam interferometer in which the phase between the reference and test paths is adjustable.
