Tweaks Turn Microscope into Billion-Pixel Imager
Changhuei Yang’s lab at Caltech has developed a new setup that converts a relatively inexpensive conventional microscope into a billion-pixel imaging system that significantly outperforms the best available standard microscope. “We found a way to actually have the best of both worlds,” said Guoan Zheng, initiator of the approach. “We used a computational approach to bypass the limitations of the optics. The optical performance of the objective lens is rendered almost irrelevant, as we can improve the resolution and correct for aberrations computationally.”
