An IR Twyman-Green interferometer is described. It uses a cw CO2 laser as a light source operating at a 10.6-μm wavelength. Theoretical analysis and experimental measurements of the relationship between the contrast of the interference fringes and the rms roughness of test surfaces are discussed. Interferometric testing results and special alignment methods are shown for rough surface optics.read more

Sub-nyquist interferometry
TL;DR: Sub-Nyquist interferometry (SNI), an extension of PSI, is described and demonstrated to overcome the inability to measure surfaces with large aspheric departures, and it preserves the measurement precision that is inherent to PSI.

Rough surface interferometry with a two-wavelength heterodyne speckle interferometer.
TL;DR: It is shown that the macroscopic surface profile may be determined from the phase differences if the effective wavelength Λ = λ1λ2/|λ1−λ2| is sufficiently larger than the standard deviation of the microscopic profile of the illuminated surface, and the statistical error is reasonably small if the phase measurements are obtained from speckles of sufficient intensity.

TL;DR: In this article, a theory has been developed that addresses two test conditions, each based on the use of a known test flat in a double-pass configuration with a collimated optical system of unknown quality.
