Abstract
Abstract Image-forming means for producing in an image plane a first image, which is derived from a holographic record, comprise a source of monochromatic light for illuminating a holographic record disposed in a predetermined second plane, and a first optical system for deriving said image from the light from said holographic record thus illuminated. The system comprises imagepresenting means, which serve to provide a second image from a non-holographic record and television signal-producing means which comprise a television camera for deriving television signals from said image in said image plane and said second image.
