Abstract
A holographic technique is described that can be used to evaluate the susceptibility to thermally induced distortion in mirror blanks prior to optical finishing. Polished blanks also can be evaluated using this technique. Primarily, this technique has been used for measuring the distortion at cryogenic temperatures; however, with minor modifications, it also can be used to evaluate mirror performance above room temperature.
