A group of scientists in MIT have created something un-imaginable – A video camera that can shoot trillion frames per second, yes..that’s right – Trillion Frames per second camera. This camera is so fast that it can produce a slow-motion video of a burst of light traveling the length of a one-liter bottle, bouncing off the cap and reflecting back to the bottle’s bottom.
And, there is a Indian connection to this invention- The super high-speed camera was developed by Indian Associate Professor Mr. Ramesh Raskar’s Camera Culture group at the MIT’s Media Lab.
Here’s what they have to say at their blog post about the new innovation :
The system relies on a recent technology called a streak camera, deployed in a totally unexpected way. The aperture of the streak camera is a narrow slit. Particles of light — photons — enter the camera through the slit and are converted into electrons, which pass through an electric field that deflects them in a direction perpendicular to the slit. Because the electric field is changing very rapidly, it deflects the electrons corresponding to late-arriving photons more than it does those corresponding to early arriving ones.
The image produced by the camera is thus two-dimensional, but only one of the dimensions — the one corresponding to the direction of the slit — is spatial. The other dimension, corresponding to the degree of deflection, is time. The image thus represents the time of arrival of photons passing through a one-dimensional slice of space.
You can have a look at the video for better understanding:
good one!
