Super-Resolution Digital Microscopy

February 1st, 2016 by

Researchers from the University of California Los Angeles have developed a new technique for digital microscopy that uses lens-free holograms. The technique, called wavelength scanning pixel super-resolution, uses a device that captures a stack of digital images of the same specimen, each with a slightly different wavelength of light. A new algorithm, which divides the pixels in each captured image into a number of smaller pixels, is then applied. The result is a higher-resolution digital image of the specimen. The significance is that researchers can now inspect large samples with finer details at the sub-micron level. The technique works when applied to both lens-based conventional microscopes and lensless on-chip micrscopy.
