Abstract
Optics manufactured in a gravitational field are made with inherent internal stresses. When these optics are removed from the gravitational field (I.E., put into space) these stresses release. This is referred to as G-release. Theory offers methods of predicting the resulting 0-G shape of these optics. The intent of this paper is to compare results of real data measured on the same mirror from two separate methods; the ‘N-1 rotation test’ and the ‘face up/face down test’.
