Humans have achieved the greatest endeavor by taking inspiration from the world around them. The ability to question the natural phenomenon or trying to understand the functioning of their own body formed the basis of most of the modern world’s advanced technology.
Cameras were invented when scientists understood the visual system of human eye. This optical instrument initially replicated the basic functioning of the human eye, now it can even capture the moments which our naked eye is incapable of.
Researchers at University of Tokyo and Keio University in Japan have invented the world’s fastest camera which can record 4.4 million frames in a single second. This camera is massive occupying around 3 square feet region and named as Sequentially Timed All-optical Mapping Photography (STAMP). It will be used to capture chemical processes and reactions such as heat conduction.
Even the most sophisticated iPhone slow motion camera records 120 frames per second and by comparison it will have to record for 1161 years to capture the same amount of frames as STAMP can in a second. However, STAMP’s resolution is not that impressive, a mere 450 x 450 pixels is considered enough for this camera.
STAMP uses a new technique called motion-based femtophotography which maps an object movement over time. The mapping is done in a ‘burst stream’ of timed photographs sequenced in correct order to show the object’s ‘time varying spatial profile.’
Previously, the fastest cameras collected the data to construct image using ‘pump probe process’. When the object is being photographed, light is pumped at the object and then probed for absorption by a laser.
The team has already managed to record heat conduction – a process that occurs at one sixth the speed of light. The researchers have published their work in Nature Photonics.
There are no plans to commercialize the camera which will only be used in medical applications and scientific research.
