Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy—a specialized imaging technique that looks for a change in the color of intense ...

Announcing a new publication from Opto-Electronic Advances; DOI 10.29026/oea.2026.250312. Bone mineral density (BMD) has long been the "gold standard" for assessing fracture risk. However, clinicians ...

A label-free optical imaging method reveals changes in cellular lipids, proteins, and metabolism following X-ray exposure.

have found a new way to image layers of boron nitride that are only a single atom thick. This material is usually nearly invisible in optical microscopes because it has no optical resonances. To ...

Researchers at Aix Marseille University show that coherent Stokes Raman scattering can intrinsically emit refocusable signal into the backward direction from homogeneous media, enabling same-side ...

Researchers have developed a new microscope that can visualize the optical response of surfaces at an unprecedented spatial resolution of one nanometer. This paves the way for optical microscopy of ...

The Biophotonics and Translational Optical Imaging Lab is dedicated to developing novel optical technologies for imaging of living systems to improve understanding, diagnosis and interventions of ...

Nonlinear excitation of fluorescence allows for excellent optical sectioning, enabling high resolution imaging deep into highly scattering tissue. Two-photon microscopy is one of the most widely used ...

Microscopy is an imaging technique that enables us to see a world that would otherwise be invisible to us. Once upon a time, visualizing cells, microbes and other entities not perceptible to the naked ...

If you think of a single atom as a grain of sand, then a wavelength of visible light—which is a thousand times larger than the atom's width—is comparable to an ocean wave. The light wave can dwarf an ...
