Instrumentation for Accurate Measurement and Control of Optical Phase for Time and Coherence Domain Communications and Space-Time Interferometry.
Abstract
Under this program, we constructed an advanced optical phase detection, control and analysis system for space time interferometry and optical communications. The system uses scanning interferometry to extract the phase and magnitude of serial and space time fields. Key components include precision mechanical stages and controllers, high quality optical elements, serial and parallel receiver arrays, broadband sources, and advanced electronic control, data acquisition and analysis subsystems. We used this system to extend our previous work on space time image capture and to systematically explore advanced phase characterization techniques. This report describes our results in using this system to characterize the SNR and information capacity of phase sensitive interferometric imaging and shows experimental evidence of super resolved scanning using phase sensitive detection.
