Abstract:

One approach for constructing ultra-large 20m next-generation, space-based telescopes is to use membrane primaries. Conventional refractive lens or reflective mirror elements require perfect three-dimensional surfaces that are impossible to create in zero-g. An alternative is to use a flat diffractive element, which removes the need for out of plane deformation. In this case, the primary is a photon sieve, a diffractive element consisting of millions of holes arranged in circular rings. A Fresnel Zone Plate FZP is a diffractive element consisting of concentric transparent and opaque circular zones.
