CLOAKING

Just mess around with the focal points of the lens to give you the illusion of cloaking .

Please note that this design is being filed for patent.


Make your own cloaking device:

1. 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)
2. 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).
3. Do the same in Step 2 for the other two lenses.
4. Separate the two sets by t₂=2 f₂ (f₁+ f₂) / (f₁— f₂) apart, so that the two f₂ lenses are t₂ apart.
