Fiber optic scanning apparatus

Claim 2

A FLYING SPOT SCANNER FOR TRANSDUCING VARIATIONS IN RADIATION CHARACTERISTIC OF A RECORD MEDIUM MOVING AT CONSTANT SPEED TO VARYING ELECTRICAL SIGNALS, COMPRISING, IN COMBINATION, FIBER OPTIC CIRCLE-TO-LINE SHAPE TRANSDUCER MEANS HAVING ITS LINE END POSITIONED ADJACENT SAID RECORD MEDIUM, ROTATABLE FIBER OPTIC RADIATION DISTRIBUTOR MEANS COMPRISING A PLURALITY OF RADIATION CONDUCTING FIBERS HAVING ONE END POSITIONED AT ITS AXIS OF ROTATION AND HAVING ITS OTHER END CENTRO-SYMMETRICALLY ALINED WITH THE CIRCULAR END OF THE SHAPE TRANSDUCER MEANS, THE RADIATION CONDUCTING FIBERS AT THE CENTRO-SYMMETRICALLY ALINED END OF THE RADIATION DISTRIBUTOR MEANS BEING SUBSTANTIALLY ARRANGED ALONG A RADIAL LINE EXTENDING OUTWARD FROM THE AXIS OF ROTATION OF THE RADIATION DISTRIBUTOR MEANS, A RADIATION SOURCE POSITIONED TO DIRECT RADIATION UPON THE AXIAL END OF THE FIBER OPTIC RADIATION DISTRIBUTOR MEANS, MOTOR MEANS FOR ROTATING THE RADIATION DISTRIBUTOR MEANS AT A ROTATIONAL SPEED INVERSELY PROPORTIONAL TO SAID CONSTANT SPEED OF SAID RECORD MEDIUM AND DIRECTLY PROPORTIONAL TO THE WIDTH OF THE CONDUCTING FIBERS OF SAID SHAPE TRANSDUCER, AND RADIATION DETECTOR MEANS POSITIONED TO RECEIVE RADIATION VARYING IN ACCORD WITH VARIATIONS IN THE RADIATION CHARACTERISTICS OF THE RECORD MEDIUM.

Claim 3

A FLYING SPOT RECORDER FOR TRANSDUCING VARIATIONS IN AN ELECTRICAL SIGNAL TO A RECORDED PATTERN ON A RADIATION SENSITIVE RECORD MEDIUM, COMPRISING, IN COMBINATION, A SOURCE OF VARIABLE ELECTRICAL SIGNALS, A FIBER OPTIC CIRCLE-TO-LINE SHAPE TRANSDUCER A MEANS FOR TRANSPORTING THE RADIATION SENSITIVE RECORD MEDIUM PAST THE LINE END OF THE SHAPE TRANSDUCER AND IN CLOSE PROXIMITY THERETO, MOTOR MEANS HAVING ITS AXIS OF ROTATION COINCIDENT WITH THE AXIS OF THE CIRCULAR END OF THE SHAPE TRANSDUCER, SUPPORT MEANS MOUNTED TO THE SHAFT OF THE MOTOR MEANS FOR ROTATION THEREWITH, RADIATION DISTRIBUTING FIBER OPTIC MEANS SECURED TO THE SUPPORT MEANS AND TRAVERSING A PATH THEREON EXTENDING RADIALLY FROM THE AXIS OF ROTATION TO A POINT ALINED WITH THE OPTICAL FIBERS AT THE CIRCLE END OF THE SHAPE TRANSDUCER TO EFFECT A CYCLICAL SCAN OF THE FIBERS AS THE SUPPORT MEANS IS ROTATED BY THE MOTOR, AND A RADIATION SOURCE CONNECTED TO AND MODULATED BY THE OUTPUT OF THE SOURCE OF VARIABLE ELECTRICAL SIGNALS, THE RADIATION SOURCE BEING POSITIONED TO DIRECT ITS MODULATED RADIATION OUTPUT ON THE AXIAL END OF THE CYLINDRICALLY SCANNING RADIATION DISTRIBUTING FIBER OPTIC MEANS WHEREBY VARIATIONS IN THE RADIATION OUTNALS ARE TRANSDUCED TO VARIATIONS IN THE RADIATION OUTPUT OF THE RADIATION SOURCE AND RECORDED ON THE RADIATION SENSITIVE RECORD MEDIUM.

Claim 4

A FLYING SPOT RECORDER FOR TRANSDUCING VARIATIONS IN AN ELECTRICAL SIGNAL TO A RECORDED PATTERN ON A RADIATION SENSITIVE RECORD MEDIUM, COMPRISING, IN COMBINATION, A SOURCE OF VARIABLE ELECTRICAL SIGNALS, A FIBER OPTIC CIRCLE-TO-LINE SHAPE TRANSDUCER A MEANS FOR TRANSPORTING THE RADIATION SENSITIVE RECORD MEDIUM PAST THE LINE END OF THE SHAPE TRANSDUCER AND IN CLOSE PROXIMITY THERETO, MOTOR MEANS HAVING ITS AXIS OF ROTATION COINCIDENT WITH THE AXIS OF THE CIRCULAR END OF THE SHAPE TRANSDUCER, SUPPORT MEANS MOUNTED TO THE SHAFT OF THE MOTOR MEANS FOR ROTATION THEREWITH, RADIATION DISTRIBUTING FIBER OPTIC MEANS SECURED TO THE SUPPORT MEANS AND TRAVERSING A PATH THEREON EXTENDING RADIALLY FROM THE AXIS OF ROTATION TO A POINT ALINED WITH THE OPTICAL FIBERS AT THE CIRCLE END OF THE SHAPE TRANSDUCER TO EFFECT A CYCLICAL SCAN OF THE FIBERS AS THE SUPPORT MEANS IS ROTATED BY THE MOTOR, AND A RADIATION SOURCE CONNECTED TO AND MODULATED BY THE OUTPUT OF THE SOURCE OF VARIABLE ELECTRICAL SIGNALS, THE RADIATION SOURCE BEING POSITIONED TO DIRECT ITS MODULATED RADIATION OUTPUT ON THE AXIAL END OF THE CYLINDRICALLY SCANNING RADIATION DISTRIBUTING FIBER OPTIC MEANS WHEREBY VARIATIONS IN THE RADIATION OUTNALS ARE TRANSDUCED TO VARIATIONS IN THE RADIATION OUTPUT OF THE RADIATION SOURCE AND RECORDED ON THE RADIATION SENSITIVE RECORD MEDIUM.
