Have you ever wanted to turn invisible? While it seems like we still have quite a way to go before we develop human-scale optical cloaks (devices that can “cloak” or hide objects), we’ve already made it partly a reality. Using mirrors, prisms, and lenses to manipulate light rays, scientists have been able to cloak tiny areas relatively easily, making ray-based cloaking tech one of the more feasible routes to take towards making everyday optical cloaks.

Hopefully, as the study’s data and methodology have been made available for others to evaluate, these prejudices can be avoided in the next iteration. Read full article here
