Abstract

We have developed diffractive primaries in flat membranes for space-based imagery. They are an attractive approach in that they are much simple to fabricate, launch and deploy compared to conventional three-dimensional optical structures. In this talk we highlight the design of a photon sieve which consists of a large number of holes in an otherwise opaque substrate. We present both theoretical and experimental results from small-scale prototypes and key solutions to issues of limited bandwidth and efficiency that have been addressed. Our current efforts are being directed towards an on-orbit 0.2m solar observatory demonstration deployed from a 3U CubeSat bus.
