Paper Abstract

The objective of this project is to dynamically align a Michelson interferometer. This interferometer is designed to measure the spatial coherence of light sources. In order to obtain accurate coherence measurements, many parameters within the interferometer must be controlled with high precision. Once such parameter is the angle of inclination between mirrors in the interferometer. To introduce a well controlled and variable amount of tilt between the mirrors, we propose here a new dynamic alignment method employing a position sensitive device. A theoretical angular precision of 1 microrad was desired and an experimental angular precision of 2 microrads was obtained.
