title: Mirror blank testing by real-time holographic interferometry.
abstract: This paper describes an application of real-time holographic interferometry to the testing of unworked mirror blanks. The thermal test of a 70-cm diam, fused silica, eggcrate mirror blank and the mechanical test of a 28-cm mirror blank are included.
