Axisymmetric Optical Membrane Modeling Based on Experimental Results

<p>The United States Air Force Department of Defense and commercial industry have recognized the great value of near-earth space development specifically in satellites for use in communications ground and space surveillance and more active roles. However resolution or the primary optic's diameter has been a limitation especially for ground surveillance. Deployable optics has been investigated to allow larger optics in space and membrane optics has received increasing attention recently. The membrane's flexible nature requires some passive and possibly active control to reduce optical distortion caused by manufacturing deployment or other effects during use. Piezoelectric surface controllers are one option to actively control the membrane on the order of optical measurements (micron displacement or less). Multiple configurations of transverse displacements are feasible depending on the piezo zone locations and activation.</p><p>This work has been selected by scholars as being culturally important and is part of the knowledge base of civilization as we know it.
