Claim 1
Independent Claim
147 words
AN ENERGY MEASURING DEVICE FOR DETERMINING THE TOTAL ENERGY OUTPUT OF A LASER COMPRISING: A BLACK-BODY ENCLOSURE HAVING AN OPENING IN THE FRONT PANEL THEREOF, A HOLL SPHERE SUSPENDED IN SAID BLACK-BODY ENCLOSURE, ELONGATED THERMAL INSULATORS ATTACHED BETWEEN SAID BLACKBODY ENCLOSURE TOP AND SAID HOLLOW SPHERE FOR SUPPORTING SAID HOLLOW SPHERE IN A SUSPENDED STATE, SAID HOLLOW SPHERE HAVING A SMALL OPENING OFF-CENTER THEREOF IN ALIGNMENT WITH THE OPENING SAID BLACK-BODY ENCLOSURE TO RECEIVE THE LASER BEAM PASSING THERETHROUGH, THE INNER SURFACE OF SAID HOLLOW SPHERE BEING HIGHLY POLISHED TO REFLECT AND DISSIPATE THE LASER BEAM WHICH ENTERS THEREINTO, SENSING MEANS ATTACHED TO THE OUTER SURFACE OF SAID HOLLOW SPHERE FOR DETERMINING TEMPERATURE CHANGE THEREOF, AND MEANS FOR DISPLAYING THE SIGNAL FROM SAID SENSING MEANS, THE TEMPERATURE CHANGE OF SAID HOLLOW SPHERE SHOWN ON SAID DISPLAY MEANS BEING PROPORTIONAL TO THE TOTAL ENERGY OUTPUT OF THE LASER.
