Worlds fastest camera shoots 4.4 trillion frames per second.
A Japanese team has created a recording device able to acquire 4.4 trillion images per second, at a 450 x 450 pixel resolution. The technique could be used to further research into heat conduction and chemical reactions, according to its creators.
If the resolution can be improved, it could also prove useful for manufacturing, where it could keep track of laser cuttings in real time.
The technique, known as a Sequentially Timed All-optical Mapping Photography, or STAMP for short, shuns the conventional methods employed by other superspeed cameras to achieve results up to 1,000 times faster than has been previously available. The current leading brand of high-speed real-time recording is a method unfortunately known as the pump-probe process, where light is “pumped” at the subject and then “probed” for absorption. STAMP differs from this by skipping the need to constantly probe, or measure, the scene to construct an image, instead it uses single-shot bursts to acquire images and maps the spatial profile of the subject to the temporal profile at a 450x450-pixel resolution.
