Seeing is  believing, right? Maybe not. The idea of making objects disappear is no longer a sci-fi fantasy.

Scientists in the US and Canada say spectral cloaking technology has been demonstrated in lab tests resulting in a breakthrough that has all kinds of potential applications, reports the Optical Society.

For starters, the approach is being hailed as a way of securing data transmitted over fiber optic lines, helping improve technologies for sensing, telecommunications and information processing, researchers say.

In concept, they say, it could be extended to make 3D objects invisible from all directions — a significant step in the development of practical invisibility cloaking technolo

While most current cloaking devices can fully conceal the object of interest only when the object is illuminated with just one color of light. But sunlight and most other light sources are broadband, meaning that they contain many colors. The new device, called a spectral invisibility cloak, is designed to completely hide arbitrary objects under broadband illumination.
