Image on the Film of a Hologram

电影中的全息图
The image on the film for a transmission hologram is formed by the interference of the light from the object and the reference beam. This interference pattern looks something like the ripples on a pond when a bunch of small pebbles is thrown in. The interference pattern on this hologram is extraordinarily well defined.

透射全息图上的图像是由物体光与参考光的干涉形成的。这种干涉图案看起来就像向池塘中投掷一堆小石头时水面产生的波纹。这个全息图上的干涉图案定义非常清晰。
Viewing a transmission hologram involves illuminating it with a coherent source like a laser and looking through the film at the image in space behind the film. The image shown is associated with the interference pattern above.
观察透射全息图需要将它用相干光源（如激光）照射，并通过胶片观察胶片后空间中的图像。所显示的图像与上方的干涉图有关。
