Dynamic Interferometry: measurement of space optics and structures

Over the last two decades the use of single-frame interferometric techniques, known as Dynamic Interferometry, have become widely available in commercial interferometer systems and they have been used extensively in the production of state-of-the-art space-based optical systems. This paper presents an overview of the techniques and configurations used to build dynamic interferometers and measurement results for a variety of space-based optical components as well as the structures that hold them under simulated space-flight conditions. These techniques and configurations have applicability for many non-space applications as well.
