The technique of wide field imaging for optical/IR interferometers for missions like Space Infrared Interferometric (SPIRIT), Submillimeter Probe of the Evolution of Cosmic Structure (SPECS), and the Terrestrial Planet Finder (TPF-I)/DARWIN has been demonstrated through the Wide-field Imaging Interferometry Testbed (WIIT). In this paper, we present an optical model of the WIIT testbed using the commercially available optical modeling and analysis software FRED. Interferometric results for some simple source targets are presented for a model with ideal surfaces and compared with theoretical closed form solutions. Measured surface deformation data of all mirror surfaces in the form of Zernike coefficients are then added to the optical model compared with results of some simple source targets to laboratory test data. We discuss the sources of error and approximations in the current FRED optical model. Future plans to refine the optical model are also be discussed.
