Paper Abstract

The "conventional" procedure in evaluating the image degradation caused by deformed optical surfaces uses only the local Z-component of the optical surface's nodal displacement vector along with the nominal X and Y-coordinates directly from a finite-element model (FEM) to evaluate a Zernike polynomial. The surface's decenter is handled separately. This method may produce significant errors if thermal loads and complex load combinations are considered. An alternative vector approach, which overcomes this problem in a single step, is presented.
