TED: Imaging at a trillion frames per second | Ramesh Raskar

The video introduces femto photography, a technique capturing images at one trillion frames per second, allowing visualization of light in motion. It explores the potential of this technology to see around corners, inspect fruit ripeness, and improve health imaging. The femto camera, developed at MIT, uses synchronized photon packets to create detailed images. Future applications include collision-avoidance systems and advanced medical imaging, though challenges remain. The video calls for a shift in focus from megapixels to time-based imaging advancements.
