title: Interferometry and holography in a low-gravity environment.
abstract: A Mach-Zehnder interferometer and a sideband holographic unit have been used in various materials processing in space (MPS) experiments conducted in a low-gravity environment. These experiments lay the groundwork required for the use of advanced optical measurement techniques in Space Shuttle experiments. The design and operation of the optical units are presented and preliminary results are outlined. The low-gravity experiments were conducted using a NASA KC-135 aircraft flying a parabolic trajectory.
