When our colleagues studying zebrafish used it for the first time, they were blown away. "If you merge multiple viewpoints together (as your two eyes do), you see objects from different angles, which gives you height. "It's like human vision," said Roarke Horstmeyer, assistant professor of biomedical engineering at Duke University. Perfecting the process of stitching together dozens of individual cameras with subpixel resolution simultaneously allowed them to see the height of objects too. Six years, several design iterations and one startup company later, the researchers made an unexpected discovery. By combining 24 smartphone cameras into a single platform and stitching their images together, they created a single camera capable of taking gigapixel images over an area about the size of a piece of paper. By the following day, the duo sorted out their software issues and demonstrated a successful proof-of-principle device on the classic children's puzzle book.
