Researchers have developed tiny translucent slides capable of producing two distinct images at the same time when viewed from opposite sides. How is this possible — and what are the implications?
Imagine a window with an image etched on its surface, but when you walk around to the other side, the image is entirely different.This allows for two distinct images to be seen when viewed from opposite sidesThough it sounds impossible, that's essentially what researchers from the Australian National University have achieved, with tiny translucent slides that can show two distinct images, at the same time, when viewed from opposite sides.
These new light-based devices could eventually lead to faster and cheaper internet, the researchers said.As you may have noticed, light usually travels along the same path forward and backward through a material like glass or water. These cylinders could be positioned to be "bright" or "dark" for only the backward or forward directions, or "bright" or "dark" for both forward and backward.
