Penn State engineers have used a "white-light laser" to produce a new type of optical "tweezers" that not only traps, holds and moves microscopic objects but also can perform ...
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 ...
Microlenses have many applications, such as coupling light into fiber optics, enhancing light source uniformity in microdisplays, and focusing light onto imaging sensors in mobile phone cameras.
Researchers have integrated their megahertz-speed optical coherence tomography (MHz-OCT) system into a commercially available neurosurgical microscope. The top left picture shows the typical surgical ...
