Scientific research has attained great heights with the use of digital microscopy
and it is changing how clinical pathology labs are run. The technique, which
relies on sensors full of pixels, has its downsides and in certain cases
produces less than ideal pictures. >
Researchers at California NanoSystems Institute at University of California, Los Angeles have developed a technique called "pixel super-resolution using wavelength scanning" that can result in much sharper images.
The technique scans the sample under the microscope repeatedly using different wavelengths of light. Using this information, a special algorithm combines the scans into one in which individual pixels are smaller than the original.
