Abstract
A mirror drive mechanism for a tilting mirror is controlled using feedback from one or more interferometric angular sensors. The wavelength of an optical beam is varied as it is fed into an interferometric angular sensor. The wavelength at which the resulting interference pattern is measured to be at a minimum intensity is determined. This wavelength is used to determine a distance quantity representative of the angular position of the mirror.
