Paper Abstract

Recently we have demonstrated that spatial frequency modulation imaging can use extended excitation sources in linear and nonlinear image modalities, is compatible with single element detection, and results in enhanced lateral resolution across the excitation beam. In this paper, we will present new methods where the SPIFI platform goes from one-dimensional to two-dimensional imaging while still exhibiting the enhanced resolution across the added dimension. Significantly, we present the physical mechanism responsible for the resolution enhancement for all imaging modalities, we provide computational models that support the physical model for the increased resolution, and finally, present experimental verification of the resolution enhancement.
