Mirage®

The Mirage® is a very special device consisting of two parabolic mirrors (the top mirror has a hole in the middle) with the concave sides facing each other. The mirrors have identical focal lengths and the Mirage® is constructed so that the focal point of a mirror coincides with the center of the other mirror (in the case of the top mirror, right where the hole is.)

Light rays from the object at the bottom of the Mirage® will reflect off of the top mirror and travel in a parallel path. Then, after the rays hit and reflect off of the bottom mirror, they will travel towards the focal point of the bottom mirror. Which of course just so happens to be at the center of the top mirror where the hole is! So you end up with a really cool ‘real’ image even though you can’t actually touch it. Amazing!
