A DIY hologram project based on AIRR ("Aerial Imaging by Retro‐Reflection") developed by Prof. Yamamoto. Using two optical component, if you count the observers eyes too it's one more :D This optical system refocuses the light-path in mid air, hence you get the impression of a floating image in mid air.

The main optical components are a half mirror (aka magic mirror) and a retroreflector. A retroreflector is like a mirror, but it reflects always the photons back to the light sources. For example, all the street signs utilises retroreflectors as a foil to get higher visibility. A similar foil is used for this project, but with a better optical quality and reflectivity value.

The half mirror is self made. The glas is cut from a photo picture frame, and a sun shield / privacy foil was applied.

The following animation shows, from the side, the light-path for the upper half of the half mirror. The blue lines are the retroreflectors, the green line is the half mirror.

The following animation shows, from the side, the light-path for the upper half of the half mirror. The blue lines are the retroreflectors, the green line is the half mirror.
