As far as I saw this stuff on trade fairs: It is a device for easy comparison
aganst a "golden" board by either switching optically ( or iuf it is
camera based, electrically) between the views golden bd and the bd to be
checked. Then the operator can see missing parts or other differences
"blinking" in the eyepieces/displays.
