Researchers turn standard microscope into billion-pixel imaging beast
A team of researchers at the California Institute of Technology, led by Professor Changhuei Yang, have figured out a way to crank their microscopy up to 11. Usually, scientists are forced between a rock and a hard place: they can have high res images of small areas or low resolution pictures of larger fields. Using a strategy known as Fourier ptychographic microscopy, Yang's team was able to computationally correct a standard microscope's low res imagery, producing a billion-pixel picture. By adding an LED array to an existing microscope -- the only hardware tweak their $200 system calls for -- the researchers were able to stitch together a 20X quality image from a 2X optical lens. The information gleaned from the LED lights was corrected entirely on a computer, making it an exceptionally cost effective way to create high res microscopic images. The team's report, published by the journal Nature Phototonics, can be read in full at the source link below.
