I think this is related to the use of lences for stereoscopic images rather than laser (or any source of energy other than the sun) for Holographic images... Am I wrong? | ||

Yes, You are wrong. Principles are totally different. Stereoscopic image is based on phisiology. You must have two images forming stereo pair an you must look with left eye on "left" image and with right eye on "right" image - so your mind will interpret this information as three-dimensional picture. You can't turn the 3d image to see it from other poin of view. Hologram is pure physics. "Holograms are truly 3D. Certain holograms permit one to walk all the way around the projected image and see it from above and below, as if the image were real." [universalreflex] Look, for examle http://www.universalreflex.com/article_understandingholographicprinciple.html (found using Google in 2 minutes) You can find more detailed explanation in 20 min. (It is so-called thin hologram that is described in article above. Thick hologram needs coherent light only to record image, not to restore.) | ||

Another difference; since holograms are an interference effect with the light itself, color images tend to scale slightly. The different wavelengths involved (different colors) will be slightly different in size. The result is that images are never very precise if in color. The bigger the image (and the closer) the more signifcant the problem. |
