Scientists have developed what may be the world's fastest camera, which can capture 10 trillion frames per second making it possible to 'freeze time' to see light in extremely slow motion. The advance may offer insight into as-yet undetectable secrets of the interactions between light and matter, according to scientists from California Institute of Technology in the US. In recent years, the junction between innovations in non-linear optics and imaging has opened the door for new and highly efficient methods for microscopic analysis of dynamic phenomena in biology and physics.
However, harnessing the potential of these methods requires a way to record images in real time at a very short temporal resolution in a single exposure.Using current imaging techniques, measurements taken with ultrashort laser pulses must be repeated many times, which is appropriate for some types of inert samples, but impossible for other more fragile ones.
