Claim 1
Independent Claim
143 words
AN OPTICAL SYSTEM FOR MAKING AN OPTICAL RECORD OF AN ELECTRICAL TRANSIENT WHICH COMPRISES A GALVANOMETER ARRANGED TO FURNISH A LATERALLY OSCILLATING NARROW BEAM OF LIGHT, A FIXED FREQUENCY OSCILLATOR DRIVING SAID GALVANOMETER, A MODULATOR CIRCUIT CONNECTING SAID OSCILLATOR TO SAID GALVANOMETER AND ADAPTED TO MODULATE THE AMPLITUDE OF THE OSCILLATOR OUTPUT IN PROPORTION TO AN ELECTRICAL TRANSIENT IMPRESSED ON SAID MODULATOR, A LIGHT BARRIER PLACED IN THE PATH OF SAID LIGHT BEAM, SAID BARRIER HAVING AN APERTURE WHOSE WIDTH IS LESS THAN THE TOTAL SWEEP OF THE LIGHT BEAM, THE ENTIRE APERTURE BEING ARRANGED WITHIN THE AREA COVERED BY SAID LIGHT BEAM, AND MEANS FOR MOVING A PHOTOGRAPHIC MEDIUM AT A PREDETERMINED RATE PAST THE APERTURE BEYOND THE LIGHT BARRIER, THE DIRECTION OF MOTION OF THE PHOTOGRAPHIC MEDIUM BEING ESSENTIALLY AT RIGHT ANGLES TO THE DIRECTION OF MOTION OF THE LIGHT BEAM.
