WebHolography is a way of making three-dimensional (3-D) picture made with a laser. It allows the holographer to make a more exact image than with photography. The holograph seems to move and change slightly to look as if it were three-dimensional. Holography uses the wave aspect of light . WebSep 12, 2024 · Holography is sometimes called lens-less photography, because it uses the wave characteristics of light, as contrasted to normal photography, which uses geometric optics and requires lenses. Figure 4.8. 2: Production of a hologram. Single-wavelength coherent light from a laser produces a well-defined interference pattern on a piece of film.
WebRuled vs. Holographic Gratings. Both reflection and transmission gratings can be further broken down into ruled or holographic gratings, which differ in the way that the groove profile is created. The grooves in ruled gratings are mechanically scribed, or cut, into the part, while the grooves in holographic gratings are optically introduced.
