In optical microscopy, high-speed volumetric imaging is limited by either the slow axial scanning rate or aberrations introduced by the z-scanning mechanism. To overcome these limitations, scientists ...

Researchers use tightly focused laser beams to image biological samples, shape materials with microscopic precision and generate displays. But using those beams in three dimensions requires more than ...

MEMS micromirror steers a laser beam in two directions while also changing the mirror’s shape to refocus light at different depths. Credit: Hunter Shillingburg / Penn State. Researchers at Penn State ...

Researchers have developed a new type of microscope that can acquire extremely large, high-resolution pictures of non-flat objects in a single snapshot. This innovation could speed up research and ...

Fraunhofer researchers have developed a very fast technology for determining whether a tumor has been fully removed—before the patient even leaves the operating theater. Using a combination of laser ...

Laser scanning microscopes are useful for all kinds of tiny investigations. As it turns out, you can build one using parts salvaged from a Blu-ray player, as demonstrated by [Doctor Volt]. The trick ...

Confocal microscopy is a specialized fluorescence imaging technique that scientists use to acquire images at greater resolution than conventional microscopy. 1 In addition to scanning the lateral x ...
