Femto-photography is a term describing ultra high speed imaging. Femto-photography of macroscopic objects was first done by a team at the MIT Media Lab lead by Ramesh Raskar. Before that the term has at least been used for certain proposed experimental procedures in experimental nuclear physics.
In their publications Raskar’s team claims to be able to capture exposures so short that light only traverses 0.6 mm (Equal to only a few picoseconds, or thousands of femtoseconds) during one exposure by combining available high end research equipment and sophisticated sampling algorithms. Raskar presented his team’s feat during TEDGlobal 2012, reaching a wider audience through viral video.
