Why so many images?Reveal
As you stand in front of the screen, light reflects off objects and passes through the screen and into your eyes, allowing you to see the objects on the other side of the exhibit. As you look through the screen you are actually looking through a series of small lenses (Fresnel lenses). These lenses focus and transmit light over large distances. Each Fresnel lens in the screen focuses the image behind it allowing the person looking at the screen to see multiple images of the person on the other side. The effect you see is similar to compound vision. Compound vision provides multiple images of the objects around you, which is how many insects and sea creatures, see.
