Today, everything from gaming to entertainment, medical sciences to business applications are using the 3D technology to capture, store and view the available media. One such technology is holography -It allows a coherent image to be captured in three dimensions, using the Refraction properties of light. Hence we are proposing a system which will provide a 3D calling service wherein a real-time 2D video will be converted to a three dimensional form which will be diffracted through the edges of the prism. The prism will be constructed along with the system. Two users who wish to communicate using this 3D calling service need to be equipped with latest smart phones having front cameras and speaker phones. Holography provides the users with a comfortable and natural like viewing experience, so this technology can be very promising and cost-effective for future commercial displays.
