Near infrared ray have the property of generating heat, irradiating the object. The optical characteristic is about the same as a visible ray of light. However, it is a little known fact that near infrared rays have thermal energy which is possible to optically transmit like optical fiber that can transmit optical information. This does not belong in any category of thermal transmission such as radiation, conduction and convection, which is designated as ”total reflection transmission”.In this paper I would like to describe the mechanism of my Infrared Guide Heating Device which has utilized and developed the above properties of infrared rays.
