Yu Chen : AM and FM Approaches to Sensing and Imaging

In radio signal encoding and decoding, frequency modulation (FM) has several advantages over amplitude modulation (AM) - we all enjoy the high fidelity and nearly static free reception of FM radio. Sensing and imaging can also be approached with AM or FM modalities. All imaging methods practiced today are AM implementations, and FM for imaging has never been explored or its advantages exploited. In this talk I'll introduce the FM approach to sensing and imaging in its infant form. I'll show that the FM approach is closely related to design of Gaussian quadratures for bandlimited functions. I'll demonstrate the superiorities of the FM approach over AM by proposing three FM methods to deal with Gibbs phenomenon encountered in imaging.
