Abstract: This device uses mirrors and the optical effect of parallax to create the optical illusion of an infinite regression of reflections in those mirrors. Mirrors are attached, facing inwards, to the four inner sides of a box, and a mirror is attached to the bottom facing upwards. Mirrors that reflect on one side but can be seen through when looking from the other side are generally known as “see through” or “one way” mirrors. The front side of the box has viewing portals and a one way “see through” mirror through which the viewer can look directly from outside the box into the line of sight for the reflections inside the box without the viewer's reflection showing in the mirrors. Thus, the viewer sees a nearly infinite chain of reflections in the mirrors because of the optical effect of parallax and because the viewer's reflection is in spite of the fact that the viewer is looking directly into a mirror because the viewer's reflection is hidden by the “one way” see through mirror in the front.

Thus, the luminance performance can be improved.

In the method, a neutron supermirror, which is widely used in the formation of thin films in cold neutron guides and the spectrometer field, is fabricated with nickel thin films and titanium thin films, having varying thickness, using a combination of monochromator structures in which nickel thin films and titanium thin films, having the same thickness, are stacked in the form of periodic structures.
