Multiple image storing system for high speed projectile holography
Abstract
Abstract A THREE BEAM SYSTEM FOR OBTAINING A HOLOGRAPHIC RECORD ON FILM OF A HIGH SPEED PROJECTILE, WHEREIN A COHERENT BEAM OF RADIATION IS DIVIDED INTO A REFERENCE BEAM, A DIRECT SIGNAL BEAM AND A REFLECTED SIGNAL BEAM. THE REFERENCE BEAM IS DIRECTED WITHOUT MODULATION TO A PHOTOGRAPHIC PLATE AND THE DIRECT SIGNAL BEAM IS DIRECTED TO THE PHOTOGRAPHIC PLATE AFTER TRANSMISSION BY THE PROJECTILE. THE REFLECTED SIGNAL BEAM IS DIRECTED INTO A BEAM STEERER WHICH ALLOWS THE SYNCHRONOUS TRACKING OF THE PROJECTILE WITH THE REFLECTED SIGNAL BEAM. ON REFLECTION FROM THE PROJECTILE THE REFLECTED SIGNAL BEAM IS INCIDENT ON THE PHOTOGRAPHIC PLATE. AS THE INCLUDED ANGLE BETWEEN THE REFERENCE BEAM AND THE REFLECTED SIGNAL BEAM CHANGES, MULTIPLE IMAGES OF THE TARGET WILL BE STORED IN THE THICK EMULSION OF THE PHOTOGRAPHIC PLATE.
