Development Of A Thermal Image Endoscopic System Using Infrared Fibre Bundles And Its Feasibility In Medical And Biological Fields (In Japanese)

This paper attempts to develop a thermal endoscopic system for use in the medical and biological fields that contains a bundle of infrared fibres made of substances such as chalcogenide compounds, which have the ability to be drawn into a thin fibre. Results so far have shown that the ratio between the set temperature of the black body and the temperature was measured by the infrared camera through the fibre bundle was about 10% and it was possible to identify and observe thermal images of the organs and tissues in an oral cavity or in an abdominal cavity through the fibre bundles; it is, however, still necessary to improve the temperature resolution of the system in order to get thermal images with the required precision.
