Claim 1
Independent Claim
213 words
A METHOD FOR DETERMINING THE DEGREE OF COINCIDENCE BETWEEN FIRST AND SECOND SIGNALS COMPRISING THE STEPS OF: RECORDING THE FIRST SIGNAL ON A BISTABLE RECORDING MEDIUM BY A BEAM OF ONE TYPE OF RADIATION AS AN ELONGATED FIRST TRACE HAVING A LONGITUDINAL TIME SCALE, THE UNIT DEGREE OF OPAQUENESS OF THE FIRST TRACE BEING REPRESENTATIVE OF THE AMPLITUDE OF THE FIRST SIGNAL; RECORDING THE SECOND SIGNAL ON A SECOND RECORDING MEDIUM, THE SECOND SIGNAL BEING RECORDED AS A SECOND ELONGATED TRACE HAVING A LONGITUDINAL TIME SCALE, THE UNIT DEGREE OF OPAQUENESS OF THE SECOND TRACE BEING REPRESENTATIVE OF THE AMPLITUDE OF THE SECOND SIGNAL; SUPERIMPOSING SAID RECORDING MEDIA WITH THE TIME SCALES OF THE TRACES IN COINCIDENCE; EXPOSING THE RECORDING MEDIA TO A CONSTANT INTENSITY SOURCE OF RADIATION, THE INTENSITY OF THE SOURCE BEING SUCH AS NOT TO APPRECIABLY CHANGE THE STATE OF THE BISTABLE RECORDING MEDIUM; MOVING AT LEAST ONE OF THE RECORDING MEDIA IN A DIRECTION TO PROVIDE RELATIVE LONGITUDINAL MOVEMENT BETWEEN THE TRACES; DETERMINING THE AMOUNT OF LIGHT PASSING THROUGH THE SUPERIMPOSED RECORDING MEDIA AS A FUNCTION OF THE TIME-PHASE RELATION BETWEEN TRACES; AND EXPOSING THE BISTABLE RECORDING MEDIUM TO HIGH INTENSITY RADIATION OF ANOTHER TYPE TO ERASE THE TRACES THEREON AND PREPARE THE MEDIUM FOR RECORDATION OF ANOTHER TRACE.
