Femto-photography forever changes high-speed imaging, capturing at the speed of light.

The introduction of femto-photography by Ramesh Raskar and his team at MIT allows us to visualize phenomena at the speed of light, a capability once considered impossible. Utilizing a streak camera and precision laser illumination, femto-photography captures sequential images at femtosecond intervals, revealing how light interacts within various environments.

This method provides an unparalleled view of light in motion, marking a significant leap from the nanosecond imaging previously used in scientific research. Each frame of a femto-photography sequence offers a glimpse into the interactions of photons, providing insights into the behaviour of light at speeds so rapid they were once unobservable. Femto-photography's influence extends beyond photography and science, prompting new explorations in both fields and inspiring technological innovations that continue to push the boundaries of what cameras can capture.
