This site is a repository for information on a few of the projects I have been working on for the past several years. Currently, the majority of this information is related to the development of pinholes, zone plates and photon sieves.
For an in depth explanation of how I produce zone plates, etc. please refer to the Zone Plates page.
I have setup my Diffractive Optics Designer software on this web site as an online service. The software will produce a multi-page PDF document with multiple photon sieves, zone plates, and a pinhole; ready for photo reduction.
