By combining two fundamentally different microscopy techniques, researchers can now measure the optical properties of a ...

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 ...

Light microscopy is a cornerstone in life sciences technology, having experienced considerable diversification since its inception. This development becomes visible when considering the distinctive ...

White light interferometry (WLI) is a contact-free optical method for measuring surface height. It uses the phase difference between the light reflected off a reference mirror and the target sample to ...

During the 1960s, researchers worked to overcome a debilitating feature of epifluorescence microscopy — background signals. Efforts began in both America and Czechoslovakia to do away with these ...
