The current design of the Space Interferometry Mission (SIM) employs a 19 laser-metrology-beam system (also called L19 external metrology truss) to monitor changes of distances between the fiducials...
Corner cube model for internal metrology system of Space Interferometer Mission (SIM) (2006)
Wang, Xu, Korechoff, Robert, Heflin, Mike, Sievers, Lisa
A corner cube (CC) articulation model has been developed to evaluate the SIM internal metrology (IntMet) optical delay bias (with the accuracy of picometer) due to the component imperfections, such...
