Paper Abstract

We present a technique to characterize and quantitatively measure the vibrational mode shapes and amplitudes of mirrors concurrently with surface figure testing. The technique utilizes a fast interferometer that does not introduce any mass loading to the test structure. We present the fundamentals of the technique, discuss sevral modes of operation, such as resonant and transient response, and analyze the operational limits. The performance of the measurement system is characterized using a small ambient test mirror.
