Principles of makinng hologram?

A white light hologram is not aluminum foil.  It's a very high quality photograph.  The way the picture was taken is what makes it holographic.  The main thing for any hologram is that a LASER hits the photographic film and another copy of the same LASER hits the object you're photographing before going to the same film.  For a white light hologram they use a slit to eliminate vertical parallax.

You can find a bunch of ways to do it on this site (URL below)\n\nIn particular, take a look at the last one:\nWith each click of the mouse a flurry of fireworks explodes from that spot on the page. You may also use your own images if you want. Great!

yes, it's a method to use space light, am sure you are a good researcher, you can try this,\nhttp://uttoransen.blogspot.com/

I dont know much but i would like to help you....u can use lenses...and a liquid similar to the vitreous humor.\nBut its really interesting that u r trying to create a Working model of human eye. Good luck.

it works by principle of multiple reflection. This is achieved by keeping mirros in an angle that the light from the base plate gets reflected by many mirrors before travelling your eyes via the cylinder. This is almost the extension of concept where people keep huge mirrors in shop to provide an illusion that it is a big shop.

ok, just follow step by step and i bet u'll be there.\n\n1)  select the area you want to have it in colour i.e. the eyes.\n\n2)  inverse the selection (press ctrl + shift + I)\n\n3)  select Image > Adjustment > Desaturate (or press shift + Ctrl + U)\n\nand you're there.

A hologram is a 3d image of an object.  If you look at one you may try to reach out and touch it but nothing is there.\n\nWe don't actually see objects, we see the light that is reflected from them.  If that light is bent somehow the image will change and the appearance of the object will be different than the case of no interference.  We try to extrapolate what was actually there based on the light that reaches our eyes (and the extrapolation is distorted if the light gets bent).\n\nIn short, the mirage is a real image, but it is not a real object.

Holography takes an impression of an image from several angles that incide at the same time on a photographic transluscent piece of film.  when the film is iluminated from the right angles with coherent light (such as lasers), the interlacing rays of light create a tri dimensional image corresponding to the original model.  Holo means "complete" and graphos means "picture".  If you cut in half the film that contains an holographic picture, you don´t get half of the picture.  Instead, you get a smaller but complete image of the original.

the chassis wont distort the reading. you need to be encompassed in a diamagnetic material for distortion.

The best simple example is the pinhole camera. An light-tight box coated black on the inside to stop reflection, with photographic paper on 1 side and a pin-hole in foil on the other side. Set up the camera and hold it steady for a short period (about a minute, experimentation required) with the pinhole exposed. When you develop the paper you will get a reasonably well focussed image that is inverted. Light from each point on the subect could pass into the camera through only 1 point, the pin-hole, and only land on 1 point of the paper. Light from the left passed through and landed on the right side of the paper and vice-versa.\n\nTo make a camera using lenses and mirrors requires far greater precision as lenses and mirrors focus light. Light from each point of the subject lands on all parts of the lens but converges to a single point again on the film. If the lens is not properly shaped, aligned and distanced from the film, the image will be out of focus. The use of mirrors and lenses allows the image to be recorded the right way around.

The ridges and flat regions on a compact disc's aluminum layer determine how laser light is reflected from that layer. As the disc turns and the player's laser scans across ridges and flat regions, the intensity of the reflected light fluctuates up and down. This reflected light is directed onto an array of silicon photodiodes that provide both the signals needed to keep the laser focused tightly on the aluminum layer and the signal that the player uses to recreate sound. The sound is encoded in the lengths of the ridges. A computer monitors the amount of light returning from the disc to determine how long each ridge is and how much spacing there is between it and the next ridge. The computer uses this information to obtain a series of 16 bit binary numbers for each of the two sound channels that are represented by an audio CD. A digital-to-analog converter uses these 16 bit numbers to produce currents that are eventually amplified and used to produce sound.

What a dope, actually this already exists.  It’s called the Focal Light Projector; also more subclassfactions of this marvel is Particle Light Projector, and the Vaporizer Particle Projector.

Your task is far more complicated than that. You will have to employ some form of adaptive optics. Atmospheric variations will cause time varying abborations and distort the image your projecting and make it look like just a big white splotch. To do a rough job of it you will need several very large mirrors with some heavy duty position control, a CCD camera and a processor to determine the amount of feedback to apply to each mirror to keep the image looking good. As far as shapes and lenses go, don't bother with the lens, just shape your mirror according to what your intending to project. Fresnel lenses are definitely out.\nThat said and done there's the size of the mirrors to deal with. If you obtained a moon sized 100% reflector then you would be able to illuminate the moon no more than what it looks like when it's full. You might be able to concentrate the light to give a brighter smaller image but it's not gonna be any good at raising international awareness.\n\nMight I suggest using the cookie cutter for it's literal use might be a better and less wasteful way of going about raising international awareness.

Use the software\n\nPhotozoom 2 Professional\n\nGives the best output for image magnification.\n\nDownload Link given below

just print out lots of color stuff until the old pinkish colors fade\n\nGot to agree thats an amusing gambit
