A hologram today may not be quite as advanced as a photographic technique as we may have seen in science fiction or fantasy shows but we can still produce holographic display technology that is quite advanced.
Holography today records light that is scattered from an object and although we haven’t quite caught up with some of the movie style holograms that are the stuff of legend, there are a series of transmission holograms that can be very helpful today for security technology. Some types of currency, credit cards and even drivers licenses will use this technology to enhance the security of an object and make sure that it can’t be duplicated easily.
A typical hologram may appear as though it’s a 3-D object or a 2-D image that has some form of depth, but it really just comes down to light and the way that our mind perceives that light. Simple holograms today use the right reflection and coordinates to create a precise 3-D image in much the same way that you would draw a 3d object. By having a light converge at a medium, it can appear to be a 3-D object from the various beams of light and the way that they hit our eyes.
The first development of this technology started in the year 1962 when a series of photographic emulsions were used to create the light mediums of objects. It would take some time before holograms would be improved and miniaturized to the point where they could be put on licenses and more.
In the future holograms could be a static effect. Special effects today for many concerts have included holograms such is artists like to pop should core of appearing live at music festivals. Although these are called holograms they are actually not true holograms. The way that these images work is by creating a strobe effect on a translucent screen to bring a high-resolution 3-D model to life.
The future of hologram technology looks bright and although we are getting more advanced with 3-D display technology on mobile devices, it could be some time before you can have your very own hologram production machine at home like in Star Trek!
