Holograms are the next evolution in computing. Microsoft has released a new type of glass capable of projecting and interacting with an Hologram
Microsoft HoloLens is the first holographic computer running Windows 10. all Universal Windows apps can be made to work as holograms. It is completely untethered–no wires, phones, or connection to a PC needed. Microsoft HoloLens allows you to place holograms in your physical environment and provides a new way to see your world.

A single-frequency light wave can be modelled by a complex number U, which represents the electric or magnetic field of the light wave. The amplitude and phase of the light are represented by theabsolute value and angle of the complex number. The object and reference waves at any point in the holographic system are given by UO and UR. The combined beam is given by UO + UR. The energy of the combined beams is proportional to the square of magnitude of the combined waves as:
If a photographic plate is exposed to the two beams and then developed, its transmittance, T, is proportional to the light energy that was incident on the plate and is given by
where k is a constant.
When the developed plate is illuminated by the reference beam, the light transmitted through the plate, UH is equal to the transmittance T multiplied by the reference beam amplitude UR, giving
It can be seen that UH has four terms, each representing a light beam emerging from the hologram. The first of these is proportional to UO. This is the reconstructed object beam which enables a viewer to 'see' the original object even when it is no longer present in the field of view.
