Abstract

A methodology is discussed for defining mirror quality requirements (as a function of spectral bandpass, type of object being viewed and type of background). The application of the methodology to several current and future large mirror systems is described. The major parameter is the surface power spectral density function; means of proper specification and measurement are discussed, along with their impact on encircled energy and scatter. The effects of diffraction are considered, including low, mid-, and high spatial frequency surface errors and surface "quilting" associated with large lightweighted mirrors.
