An experimental beam combiner (BC) is being developed to support the space interferometry program at the Jet Propulsion Laboratory.
The SIM metrology subsystem utlizes cornercube retroreflectors as fiducials.
The Micro Arcsecond Metrology Testbed (MAM) is a laboratory-based, long baseline, white-light interferometer inside a vibration-isolated vacuum tank.
The micro-arcsecond metrology testbed (MAM) is a high-precision long baseline interferometer inside a vibration-isolated vacuum tank.
The Space Interferometry Mission (SIM) relies on the combination of interferometry with a metrology system capable of measureing picometer relative length changes and micrometer absolute lengths.
This paper describes the design and performance of a brassboard astrometric beam combiner. The beam combiner was developed as part of the JPL Interferometry Technology Program (ITP). The purpose of this program is to test out design concepts in hardware that will eventually be used for the Space Interferometry Mission (SIM).
A retroreflector is an optical device that reflects light (visible, UV, or IR) in the direction where it came from.
Space-based interferometers dedicated to wide-angel astrometry would dramatically increase the accuracy of angular measurement fundamental to a wide range of astrophysical problems. The propsosed global Astrometric Interferometer for Astrophysics (GAIA) a continuously rotating instruments comprising two or three interferometers, will reach the 5-20 mue as level on more that 35 million objects.
The proposed New Millenium Interferometry consists of three spacecraft separated by up to several kilometers. A heterodyne laser metrology system is proposed to measure the relative distances between the spacecraft.
