Abstract
We have developed optical measurement and control techniques that allow stable, precise adjustment and tracking of Fabry-Perot plate parallelism and spacing over a distance of many fringes with a precision of 20 nm. This extension of the range of optical position sensing has proved useful in controlling a cryogenic, electromagnetically driven, infrared spectrometer for astronomy.
