The Optical Systems Characterization and Analysis Research (OSCAR) project was formed in 1994 to look at advanced optical modeling methods, utilizing phase retrieval, to model the optical point spread function of the Hubble Space Telescope (HST). OSCAR developed these techniques and accurately modeled the HST response and further developed maximum entropy deconvolution algorithms and mined the database and published seminal scientific manuscripts. OSCAR subsequently got involved in the Next Generation Space Telescope (NGST), now the James Webb Space Telescope (JWST), and in JWST testbed development. OSCAR has further expanded to include interferometric and coronagraphic systems such as the Stellar Imager (SI) and Terrestrial Planet Finder (TPF). This monograph details some of the work OSCAR is and has been involved in. OSCAR is science driven, thus requiring involvement, which gleams hard science, and does not function as an engineering support center.
