Abstract
Current space-based imaging platforms are significantly constrained in both size and weight by the launch vehicle. Increased payload size and weight increases the cost and decreases the selection of launch vehicles. The challenge of membrane optics in space is implementing adaptive optics technology via a membrane surface that provides at least rough order of magnitude imaging—enabling a large lightweight imaging system where small can be eliminated by processes such as real time holography. A system was developed which categorizes surface properties of optical quality membrane material with the ability to interpret membrane mirror deformation. Membrane mirrors with adaptive control were constructed and analyzed using this system which provided sub-micron deformation data with associated optical aberrations, proving the ability of PVDF film to provide adaptive control to regions of interest on membrane mirrors. Remaining technical challenges include bonding methods and eventual multi-layer laminate bonding of the PVDF control surfaces to the membrane.
