In optics, when a collection of nonlinear processes act together on a pump beam, the resulting spectral broadening of the original pump beam gives rise to a supercontinuum. Supercontinuum sources for optical coherence tomography ...
Optical coherence tomography (OCT) is a light-based imaging technique currently used in clinical diagnostics to examine organs in vivo. The technique uses interferometry; in which light reflected from an examined object combines ...
Eye doctors soon could use computing power to help them see individual cells in the back of a patient's eye, thanks to imaging technology developed by engineers at the University of Illinois. Such detailed pictures of the ...
