One of the primary challenges in advanced manufacturing (AM) is the lack of efficient optical metrics for ensuring quality control over the manufacturing process. Many current imaging techniques have excessive data requirements and require computatio

We introduce a method to enable optical amplification of a coherent Raman spectroscopy signal, which we call radio frequency (RF) Doppler Raman spectroscopy. In this article, we consider the perturbation of a probe pulse in a sample due to an excited

We introduce a new form of tomographic imaging that is particularly advantageous for a new class of super-resolution optical imaging methods. Our tomographic method, Fourier Computed Tomography (FCT), operates in a conjugate domain relative to conven

Conference on Lasers and Electro-Optics.
We present a novel single element detector imaging scheme in which spatial information is encoded into the spectral content of a broadband source. The technique is confocal when delivered with optical fiber.

In recent years, we demonstrated a new approach to super-resolution microscopy based on driving a nonlinear interaction with a Spatial Frequency Modulated Imaging (SPIFI). SPIFI is a line imaging technique that linearly sweeps all the frequencies sup

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 e
