Diffraction phase microscopy: monitoring nanoscale dynamics in materials science [Invited]

Posted on 07/28/14 by Taewoo

PDF Link Quantitative phase imaging (QPI) utilizes the fact that the phase of an imaging field is much more sensitive than its amplitude. As fields from the source interact with the specimen, local variations in the phase front are produced, which provide structural information about the sample and can be used to reconstruct its topography […]

Inverse scattering solutions using low-coherence light

Posted on 07/24/14 by Taewoo

PDF Link We present a new wave-vector-space approach for solving inverse scattering problems. In our formulation, the theories for diffraction tomography and coherence gating are combined to explain 3D reconstruction with low-coherence light. Specifically, we apply this method to solve the scattering problem with broadband fields for transmission and reflection measurements. Our results can be […]
