摘要:
A data recording camera capable of recording a data image on film as well as observing the data image through the view finder is disclosed. A beam splitter directs the light beam coming from the data to the film and view finder. The inner surface reflector of the beam splitter forms a ghost beam which forms a ghost image of the data on the film. The ghost image of the data is removed by a polarization filter (polar screen), wedge prism or thick glass plate.
