Stress Coatings for Large Scale Membrane Mirrors (preprint)

Abstract

Finite element modeling and design need further adjustments, but have shown good correlation through successful results and actuator influence. Active boundary control effective in correcting mounting errors and other types of low order aberrations typically seen in membrane applications. Spherical aberration can be controlled (as required) thought varied stress coatings on the membrane. Improvements must be made to ensure no increase in surface roughness of membrane. Deposition rate and dwell time adjustments. Testing will continue at AFRL with inclusion of real-time DN secondary.
