摘要：

The visualization technique using an infrared radiometer has been widely used to estimate the two-dimensional temperature distribution on a surface. Infrared radiometry is a nondestructive remote sensing technique and is applicable to various engineering problems such as invisible flaw detection, heat transfer measurement and so on. It is important to analyse its fundamental characteristics to establish a practical technique of measuring temperature. We therefore discuss them experimentally using infrared radiometers with three detection wavelength bands, The radiative properties near ambient conditions are proposed for various non-metal surfaces, where the grey-body approximation may be applied.
