AN APPARATUS FOR DETERMINING THE DIFFERENCE IN TEMPERATURE BETWEEN A FIRST POINT ON THE SURFACE OF A BODY HEATED TO AN ELEVATED TEMPERATURE AND A SECOND POINT IN THE BODY INACCESSIBLE BENEATH THE SURFACE, SAID APPARATUS COMPRISING MEANS FOR MEASURING THE TEMPERATURE OF THE BODY AT THE FIRST POINT, MEANS FOR MEASURING THE TEMPERATURE OF THE BODY AT A PLURALITY OF FINITE POINTS ON ITS SURFACE SPACED AT DIFFERENT DISTANCES FROM THE FIRST POINT, COMPUTING MEANS OPERATIVELY CONNECTED WITH SAID TEMPERATURE-MEASURING MEANS FOR GENERATING A FIRST SIGNAL REPRESENTATIVE OF A LINEAR DISTANCE STARTING AT THE FIRST POINT AND EXTENDING ALONG THE SURFACE OF THE BODY OVER WHICH DISTANCE THE TEMPERATURE VARIATION BEARS APPROXIMATELY A DIRECT RELATION TO THE TEMPERATURE VARIATION BETWEEN THE FIRST AND SECOND POINTS, MEANS FOR SELECTING FROM THE FINITE POINTS THE POINT WHICH IS SPACED FROM THE FIRST POINT BY A DISTANCE MOST NEARLY APPROXIMATING THE DISTANCE REPRESENTED BY SAID FIRST SIGNAL BUT BEING AT LEAST AS GREAT AS THIS DISTANCE, AND MEANS OPERTIVELY CONNECTED WITH SAID TEMPERATURE-MEASURING MEANS FOR UTILIZING THE TEMPERATURE MEASUREMENTS AT THE FIRST POINT AND THE SELECTED FINITE POINT TO GENERATE A SECOND SIGNAL PROPORTIONAL TO THE DIFFERENCE IN TEMPERATURE BETWEEN THE FIRST AND SECOND POINTS.
