A hologram represents a recording of information regarding the light that came from the original scene as scattered in a range of directions rather than from only one direction, as in a photograph. โ€ฆ In a hologram, the two intersecting light wave fronts form a pattern of hyperboloids โ€” three-dimensional shapes that look like hyperbolas rotated around one or more focal points. A hologram is a three-dimensional (3D) projection that appears to exist in physical space without requiring special glasses or screens. Itโ€™s created using light diffraction to display a fully โ€ฆ

A hologram is a picture of a "whole" object, showing it in three dimensions. We've all seen cheap hologram images on credit cards and ID cards (where they help prevent copying). Holograms provide a realistic visual experience that captures three-dimensional images without the need for special tools, like 3D glasses. This effect is created through holography, โ€ฆ Holograms create three-dimensional images by using light interference patterns from laser beams. Lasers make holograms because their light is coherent, meaning it has the same โ€ฆ The hologram does not change the wavelength (color) of light but controls how light is re-directed. There are a number of distinct types of art holograms that can be defined by their optical-geometry โ€ฆ The name hologram means โ€œentire pictureโ€ (from the Greek holo, as in holistic) because the image is three-dimensional.
