Abstract

A grazing incidence interferometer was developed at LMSC to sample the surface figure of large adaptive mirrors along narrow swaths utilizing small optical components mounted along the perimeter of the mirror. Preliminary tests have been conducted to determine the statistical limitation to the figure sensing resolution due to vibration of optical components and electronic noise. The results of these tests are discussed and plans for additional tests described.
