How Accurately Can Your Interferometer Interpolate Fringes?

Abstract

Optical interferometry is the means by which real-world displacements are measured relative to a standard reference wavelength. Most interferometers use a helium-neon laser and generate a signal with a period of half the wavelength, λ/2=316.5 nm. To resolve smaller distances, the system must perform fringe interpolation.
