PDF Link A common-path interferometer was designed with rapidly tunable broadband swept laser source, which provides quantitative phase measurements of...
PDF Link In off-axis interferometry, we usually have to deal with the unwrapping process, which is very computationally intensive and...
PDF Link We introduce a label-free method for detecting high-grade prostatic intraepithelial neoplasia (HGPIN) in unstained biopsies. We image this...
PDF Link We present epi-diffraction phase microscopy (epi-DPM) as a non-destructive optical method for monitoring semiconductor fabrication processes in real...
Prof. Popescu was invited to testify in the Congressional Hearing regarding “Innovation Corps: A Review of a New National Science...
PDF Link We present a phase derivative microscopy technique referred to as gradient field microscopy (GFM), which provides the first-order...
PDF Link We present Laplace field microscopy as a method for generating intrinsic contrast of transparent specimens. This technique uses...
