How Hologram Technology is made كيفية عمل تقنية الهولوجرام

printing variations of an image in layers then having light reflected from those services at different angles is basically how you produced hologram some mysterious not for much longer hologram is three-dimensional photographs produced by the interference of two laser beams laser emits light this light rain the color of the light varies according to the wavelength shudder when activated either blocks the light rail or let's have passed through to the be misled into 90 degree angle the interference of the two beams is clearly visible on the screen it has very defined fringes the beams need great stability because the pattern of interference projected on the screen is extremely sensitive to my new collaborationist light tap on the table can be easily spoil it completely the team will create hologram from the sculpture made of modeling clay the sculpture is positioned on support for the magnetic base which adheres to the metallic table then they place class in front of the object here's the exact point with light beam passes the table has to be perfectly stable so it's made of 2.2 ton block of steel which rests on 18 heir to the table and laser of us well insulated from all vibrations the beam splitters separates the beam into directing one behind the object in the other in front of it one part of the beam heads toward the front of the sculpture the beam first passes through an objective lens which diffuse the light then it's reflected by parabolic mirror which prevents it from losing too much of its intensity as in photography film is required this holographic film is attached to glass plate with adhesive tape then another glass plate has added so that the film will not move the vibration of one-tenth of the lasers wavelength is tolerable now the laser is turned on the intensity of its late Ray reaches about 250 milliwatts the normal exposure time of the model to the beans about one second but some holograms made with pulsed laser are exposed to the light for 12 90 seconds and infinitely short period of time here we see the reference beam coming from the parabolic mirror and here we see it from another angle as in photography the film has to be developed these trays contain different chemical solutions and the developer first two films so to the developer for two minutes this solution black and silver salts which have reacted to the light then the film is soaked in solution called bleach to completely eliminate the silver salts which black in it now the film is RIM's this step is used to eliminate the assets in the emotion and to not contaminate the next solution the film gently becomes transparent its then rinsed in Clearwater and it's okay for one minute in wetting agent which eliminates all water sparks the film is then dried and reveals its secrets and here's the hologram created from the sculpture hologram really creates three-dimensional illusion some holograms can be animated they are generated from series of still holograms depending on the complexity of the project hologram to be produced in between one and five hours
