A THERMAL RADIATION HEAT SOURCE AND IMAGING SYSTEM FOR BIOMEDICAL RESEARCH

摘要

The purpose of this investigation was to provide a more advanced radiant heat source capable of heating an area of 1 cm with up to 15 cal/cm –sec of radiant heat flux with a uniformity of + 1 percent. The source and the op¬tical imaging system were to provide a high degree of stability and reproducibility for extended periods. The imaging system is to be used in a study of the effects of intense thermal-radiation on living tissues being carried out at the U.S. Naval Air Development Center in Johnsville, Pennsylvania.nThe specified radiant heat flux and uniformity has been achieved by using a resistance heated graphite element, 16 iron wid6 find 38 mm long, as the radiation source in conjunction with a compound thermal imaging system. A heat flux-redistributor installed external to the system provided the desired flux uniformity. The completed system and source are shown in Figures 1, 2 and 3. An operation manual for the source and imaging system is included as an Appendix to this report.
