Optical Synthetic Aperture Techniques
Abstract
Optical synthetic aperture imaging concepts and techniques were theoretically and experimentally investigated. THe theory of optical synthetic aperture imaging was extended to arbitrary geometries and to multiple sources/receivers. Scanned synthetic aperture imaging was demonstrated at a wavelength of 1.22 mm. A bandwidth compression technique was analyzed and demonstrated that gave fine range resolution with only a narrow passband receiver using mode-locked lasers. A coherent optical spectrum analyzer that uses a tapped optical fiber was conceived and experimentally demonstrated. Special backprojection concepts were conceived that can process certain types of synthetic aperture data. Grating interferometer processing techniques were also investigated. (Author)
