Holography 全息投影


Holography 全息投影

全像術(英语:Holography),又稱全息投影、全息3D,是一种记录被摄物体反射(或透射)光波中全部信息(振幅、相位)的照相技术,而物体反射或者透射的光线可以通过记录胶片完全重建,仿佛物体就在那里一样。通过不同的方位和角度观察照片,可以看到被拍摄的物体的不同的角度,因此记录得到的像可以使人产生立体视觉。

這些圖像是通過全息投影產生的。使用特殊設備將圖像投影在健身房 中。這個房間裡沒有一滴水。

Holography is the science and practice of making holograms. Typically, a hologram is a photographic recording of a light field, rather than of an image formed by a lens, and it is used to display a fully three-dimensional image of the holographed subject, which is seen without the aid of special glasses or other intermediate optics. The hologram itself is not an image and it is usually unintelligible when viewed under diffuse ambient light. It is an encoding of the light field as an interference pattern of seemingly random variations in the opacity, density, or surface profile of the photographic medium. When suitably lit, the interference pattern diffracts the light into a reproduction of the original light field and the objects that were in it appear to still be there, exhibiting visual depth cues such as parallax and perspective that change realistically with any change in the relative position of the observer.

These images are created by holographic projection. The images are projected in a gym using a special device. There is not a drop of water in this room.
