Dual-Comb Photothermal Microscopy
Peter Chang, Ragib Ishrak, Nazanin Hoghooghi +4
We introduce a new parallelized approach to photothermal microscopy that utilizes mid-infrared dual-comb lasers, enabling simultaneous measurements at hundreds of wavelengths. This…
Mid-Infrared Hyperspectral Microscopy with Broadband 1-GHz Dual Frequency Combs
Peter Chang, Ragib Ishrak, Nazanin Hoghooghi +7
Mid-infrared microscopy is an important tool for biological analyses, allowing a direct probe of molecular bonds in their low energy landscape. In addition to the label-free extrac…
sCWatter: Open source coupled wave scattering simulation for spectroscopy and microscopy
Ruijiao Sun, Rohith Reddy, David Mayerich
Several emerging microscopy imaging methods rely on complex interactions between the incident light and the sample. These include interferometry, spectroscopy, and nonlinear optics…
Rapid hyperspectral photothermal mid-infrared spectroscopic imaging from sparse data for gynecologic cancer tissue subtyping
Reza Reihanisaransari, Chalapathi Charan Gajjela, Xinyu Wu +8
Ovarian cancer detection has traditionally relied on a multi-step process that includes biopsy, tissue staining, and morphological analysis by experienced pathologists. While widel…
