This is the device that scans Tom Cruise's eyes on the Steven Spielberg movie 'Minority Report'.
Such props are clearly seen in various scenes in the movie, to include close up shots with Tom Cruise.
The operating wire is in place within the prop to enable it to illuminate but it's currently in unfunctional state.
The prop is displayed upon a bespoke made acrylic display plinth.
