5 Holographic Imaging
5.1 This is a technique where images are made to appear 3D and to look like they have depth. Holograms work by taking 2 normal 2d images and layering one on the other. The 2D images must be shot at different angles.
5.1.1 E.G: Sensors/Biosensors, Microscopy, Medical Uses, Art work etc
6 Quantum Cryptography
6.1 Quantam Cryptography is technology which allows messages and data to be sent with complete privacy. Quantam crypography encrypts the data using physics so that it is impossible to break unless you have the code. Messages are encrypted using photons, these are tiny packets of light.
7 3D Printing
7.1 Making 3D solid objects from a digital file
7.1.1 It is done by laying down successive layers of material until the desired object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object
