Recorder using fiber optics
Abstract
Abstract A RECORDER FOR VISUALLY RECORDING ON LIGHT SENSITIVE FILM AN INPUT SIGNAL WHICH QUANTITATIVELY VARIES OVER A PERIOD OF TIME. THE INPUT MAY COMPRISE A FORM OF SPIROGRAPH IN WHICH A VARIABLE FLOW OF AIR ROTATES A SHAFT THROUGH A FAN. THE SHAFT IN TURN MOVES ONE END OF A FLEXIBLE OPTICAL FIBER WHICH IS ALIGNED WITH THE ENDS OF THE FLEXIBLE OPTICAL FIBERS IN AN ARRAY LONG ONE AXIS IN RESPONSE TO THE MAGNITUDE OF THE INPUT SIGNAL. LIGHT PROJECTED THROUGH THE ONE FIBER IS SELECTIVELY DISTRIBUTED TO THE ARRAY IN RESPONSE TO THE MAGNITUDE OF THE INPUT SIGNAL. SIMULTANEOUSLY THE OTHER END OF THE FIBER ARRAY IS MOVED ALONG AN ORTHOGONALLY RELATED AXIS OVER A SELECTED TIME PERIOD BY A MOTOR DRIVE SO THAT THE QUANTITATIVE MEASURE OF THE INPUT INFORMATION IS MEASURED IN TIME RELATION BY IMPINGING THE LIGHT FROM THE FIBER ARRAY ONTO THE LIGHT SENSITIVE FILM.
