Abstract

A laser graphics display is provided to produce three dimensional (3D) hologram projections. A hologram is produced by measuring the speed and distance of a laser beam, turning off the beam at a certain destination, and replacing it with another laser beam to get an image. Light sensitive pads detect the laser beam, and a clock determines the distance that the beam has travelled. Lasers are cycled to produce an image. A colour (red, green and blue) hologram may be displayed, using a laser array that forms a laser screen of dimensions 4cm by 6cm, providing a 400 by 600 display; this gives 80000 lasers for each of red, green and blue, and 720000 individual lasers. The laser graphics display is a laser screen and a lens that projects 3D Hologram, suitable for computers. As shown, lasers in the array may be in a triangular arrangement.

Description

Description
Laser graphic display L.G.D.
Laser graphics display is calculations of laser beams to produce a image with a switch to turn on the laser and a fast clock and light sensortive pads to tell how far the laser beam has gone you can measure the laser beams of each colour red, green, blue for there speed and distance.
By turning the laser off when it gets to distination say 1 mm or 6 foot you must replace the laser with another laser so the inlage stays, this is why I have designed 3 lasers per colour a lop laser, bottom right laser and a bottom left laser the top one should turn on first then just before turning off the bottom right should turn on then bottom right laser turns off then before bottom right laser turns off the bottom left laser turns on and the cycle start again even if the colour upside down the cycle should stay the same. 2.

Claims (4)

  1. Claims 1. L.G D is to produce 3D Holagram projections.
  2. 2. 3D Holagrams work by measuring speed and distance of laser beam by turning off the laser beam when get to there distination and replacing with another laser beam you can get a image.
  3. 3. There are three primary colours red green and blue laser beams hut lots of lasers because each colour is 0. I of mm all colours together are 400 by 600 becauce the screen witch holds all of laser is 4 cm height 6 cm width which in total is 240000 colours 80000 red 80000 green 80000 blue and 720000 individaul lasers.
  4. 4. L.G.D is a laser graphic display lens so computer can project 3D Holagrams.
