Research group at Lund University in Sweden has developed a superfast camera that can capture images and videos at a rate faster than the current cameras having the rate of one lakh images per second.
The new camera films at a rate of about five trillion images per second which is too fast for any filing done till date. The current camera captures one image at a time, thus clicking different images one after another. But the new camera uses an exceptional algorithm that captures many coded images in a single picture. It later sorts it in sequence.
Object to be filmed is exposed to light using laser flashes where each light pulse is given a unique code. The object reflects the light pulse and they are captured in a single photograph initially, which are later sorted as per the codes.
The use of these cameras as of now is intended for research purposes wherein the camera has the capability to film the exact details of every step in object transformations in different stages.
It can film very short spanned processes like explosions, brain activities and chemical reactions with utmost detailing so that they can be studied later by analysing every detail of transformations happening in such processes in slow motion which is usually not possible by naked eye due to quick occurrence of the event.
This camera enables the filming of many such chemical, biological and biomedical processes which couldn’t be filmed by any camera with utmost detailing till date.
