Build your own Rochester cloaking system to make objects invisible
posted December 3 2014 19:44.27 by Giorgos Lazaridis

Some time ago I posted a news article on this relatively new scientific tech. It is actually a set of four lenses with their centers aligned. The effect they create is that they light rays focus and then diverge out bending the light around a specific area. Anything that exists within this area is simply... cloaked and you still can see the background

Here is a video explaining how this phenomenon works:

 Purchase 2 sets of 2 lenses with different focal lengths f1 and f2 (4 lenses total, 2 with f1 focal length, and 2 with f2 focal length)Separate the first 2 lenses by the sum of their focal lengths (So f1 lens is the first lens, f2 is the 2nd lens, and they are separated by t1= f1+ f2).Do the same in Step 2 for the other two lenses.Separate the two sets by t2=2 f2 (f1+ f2) / (f1 14 f2) apart, so that the two f2 lenses are t2 apart.

Youtube user brusspup followed the instructions and this is his own Rochester cloaking device
