3Introduction
This technology was developed by Mr. Ramesh Raskar and his team at the MIT photography lab .
The main purpose of developing these technology is to increase the frame capacity “By having the Trillion FRAMES per second.”
Where the present pico (10^(-12)) photography is able is produce only 1 million frames per second.

• This photo was taken by Dr. Harold E. Edgerton in 1964.
• The duration of the flash in this photo is about 1/3 microseconds.

5What is Femto Photography?
Femto photography is the advanced technology of the pico photography
It is a new imaging technology which can create a light in a motion
Femto photography can visualizes the world around one trillion frames per second

7PRINCIPLE BEHIND THE TECHNOLOGY
A packet of photons are released which travels around with the speed of the light (Million times faster than ordinary bullet)
The motion/scattering of the packet can shows the light in motion
Each reflected photons reach the camera at different times (each photon frame can forms a individual raw frame)
These frames combine to develop the replica of image
8Corner Photography
The seemingly impossible task of recording what is beyond the line of sight is possible due to ultra‐fast imaging.
A new form of photography, Femto-photography exploits the finite speed of light and analyzes 'echoes of light'.

Applications
Collision Avoidance

Cardio scope
Motion Beyond Line of Sight
25Advantages
This is used to analyze the material properties and faults in industries
We can construct the camera which captures more than a million frames per second
We can recover the 3 – dimensional shape of the objects which can’t done by present 3-D cameras
26Disadvantages
We can NOT capture the arbitrary event at pico second time revolution
The data of the image captured will be too high
The work with the photons may create some health problems
