Fresnel Lens Condenser for a Solar Sail

Authors: Kenneth C. Johnson

A solar-sail spacecraft propulsion concept uses a large Fresnel lens to concentrate radiation onto one or two small beam-steering mirrors. The lens itself does not effect significant momentum transfer from the photon flux; it only functions as a condenser, which allows the use of much smaller mirrors as momentum-transfer elements.
