The Cost-Effective Hologram Technology

Holograms do not need to be a mysterious technology anymore. You can now formulate these with great ease. All theoretical obstacles are out of the way now. The credits for this goes to the recent developments brought forth by MIT’s Media Lab that brings forth holographic displays at a much lower price. The paper was recently published in a famous magazine where Daniel Smalley explains his idea for an ideal definition, holographic video, and completely colored displays. The invention created by Smalley is a small $10 optical chip that was developed in the Media Lab.

The main breakthrough came in when he was able to direct light through crystal that facilitates the holographic image of the display. The display created by Smalley has a small lithium niobate crystal in the core of complete functionality. The underside of this has been stippled with small microscopic channels that are called as waveguides, these can be used to restrict and direct the lights that will finally make up the image of display. These have been embedded with an electrode that offers an acoustic wave.

The blue, green, and red light beams pass through the crystal waveguides, the embedded electrodes formulate an audio wave that can filter out all colors that are not needed by the image. Finally, the binary channeling provided over the waveguides surface along with the audio frequency permits Smalley to generate a high quality holographic video signal, the price of this complete process is as much you may have paid for your breakfast yesterday. Smalley’s advisor adds, “Everything else in their costs more than the chip. The power supplies in their cost more than the chip. The plastic costs more than the chip.” There are a number of companies that are pursuing this technology at the moment and in recent future you are bound to see holographic TVs on your wall.
