Abstract

The infrared radiometer has been used in various fields to measure and visualize the radiation temperature distribution on the surface of a material. Radiation energy measured by the infrared radiometer is summation of an emitted radiation and reflection, which is called a radiosity flux. The present paper shows characteristics of the radiosity of tested materials and represents special keynote parameter such as the variance of radiation temperature, cavity- effect, area effect and so on. Application studies had been undertaken to detect surface and internal flaws of tested materials by an active thermal incidence and to measure the erosion rate of the graphite by ion beam injection. The temperature distribution of a cutter and an elimination of the reflecting energy based upon an irradiation of the material was studied experimentally.
