It goes without saying that Sony, Nikon and Olympus are big camera manufacturers and they are all Japanese. In fact, the country doesn’t seem to stop making advancements in the field of digital optics, especially if we talk about cameras. A joint group of researchers working at two separate Japanese universities have come out with a camera that’s 1,000 times faster than existing high-speed cameras.
Developed by the University of Tokyo and Keio University, the world’s fastest camera can capture images such as chemical reactions, lattice vibrational waves, plasma dynamics, even heat conduction, in a single shot.
Using a new technology called Sequentially Timed All-optical Mapping Photography (STAMP), the camera’s optical shutter enables it to shoot images consecutively in less than one-trillionth of a second.
Prior to the announcement in Japan, high-speed photography relied on the pump-probe process—where light is “pumped” at an object to be photographed, and then “probed” for absorption.
“The main drawback to such an approach is that it requires repetitive measurements to construct an image. The new camera is motion-based femtophotography, performing single-shot bursts for image acquisition, which means it has no need for repetitive measurements,” according to a report.
Researchers are of the opinion that their camera could make a difference, in both the public and private sectors, in a variety of fields. Some examples would be laser processes used for making big items like car parts, or in tiny applications such as the creation of semiconductros.
