Abstract

The purpose of this paper is to illustrate the rapid response of lightweight mirror blanks to small thermal perturbations and also to show how a Zernike polynomial representation of an optical surface can be helpful in analyzing the time varying deformations of the surface. In this work, a localized thermal load was introduced into the back of a lightweight mirror blank while the front surface was monitored interferometrically. Interferograms were taken every minute for the 14 minute application of the load and then continued for another 24 minutes to show the thermal relaxation of the blank.
