Principle/Philosophy

• If the film moves at the speed which follows the moving projection of a certain point, this point will always be projected on the same spot on film and will not appear unsharp.
• In OPG, the film is attached to a rotating system and moves in opposite direction to the beam. The film is given correct speed by apposing this movement with contrary movement relative to the beam.
