Last week Apple applied to the U.S. Patent and Trademark Office for a new patent named the "Interactive three-dimensional display system."
The display makes an illusion of an advanced hologram that can be touched and manipulated with the gestures of each user. It is constructed of 3 parts: a display system that produces the primary 3D image, an optical system that converts the first image into a secondary 3D image, and a sensor assembly for logging users input. The complete system is supported by a processing unit and a control circuit. It is not a new invention and it has many similarities to the generic mirror box, but Apple says it's far more complex than the others, because it doesn't rely only on an optical illusion to work.
The image is digital, not a reflection. The difference is that Apple uses infrared lasers or other devices that emit light and project an image onto a medium, such as a non- linear crystal.
The medium is located between two parabolic mirrors and it serves as an optical frequency-up converter for the light. The first image is reflected onto the upper mirror and then onto the lower mirror, and as a result a secondary hologram-like image appears above the upper mirror. They say it is not a true hologram, but the effect is very similar.
In 2011 Microsoft Research presented their invention called “Vermeer” which is a 360-degree viewable display. So the question is now, is Apple inventive enough when it comes to sci-fi hologram?
