The LCD panel of the Magic Mirror is hidden behind the partial mirror, and it is popular for a reason-they are a nice way to display useful information. A “magic window”, However, this is a completely different thing-from the looks of it, a cooler one.
If you have never seen a magic window before, don’t worry-part of the reason is that you shouldn’t have seen it. The magic window looks like a piece of transparent glass or plastic with a little wave inside, which will cause some deformation when viewed through it.But as [Matt Ferraro] Explain that distortion encodes a hidden image that is only visible when light passes through the window. It looks a bit like paraffin, but it is projection rather than reflection, and it relies on an optical phenomenon called caustics. If you have ever seen bright and dark spots on the bottom of the pool when the sun hits the bottom of the pool, you will see caustics.
As for how to hide the image in a clear window, we say that something needs to be done.There is also some mathematics; Snell’s law, Fermat’s theorem, Poisson equation-all these and more are mentioned [Matt] As an explanation. The short story is that the image is deformed, standardized and converted into a height map in the software, which is used to generate the tool path of the CNC router. The design is carved on an acrylic board by the router and polished back to clarity with a series of sandpapers. Then the wavy window is ready to cast its hidden shadow.
Honestly, the results were amazing, and we marveled at the skills needed to achieve this goal.Or more accurately, that [Matt] It can make the process simple enough for anyone to try.
