Paper Abstract

At present metal-optical research is of great academic and practical interest, since discovering the way of electromagnetic field and substance interaction allows to study the structure of different substances, find out their specific optical characteristics and obtain an opportunity of their future identification. Reflection factor is one of major experimental parameters of the matter characterizing its interaction with electromagnetic radiation. Measuring its values for low-power optical and IR radiation allows to develop ways and means of non-destructive surface control and know the composition of the specimen studied. This paper considers the techniques and offers a device to investigate surface reflection ability in vacuum under powerful thermal effect. On the basis of Taylor's sphere. A sensor-analyzer has been developed to study the surface of the material inaccessible for direct physicochemical study by conventional methods. Measurement were taken in vacuum up to 10 mTorr with heating from 20 degrees Celsius to 1700 degrees Celsius for the Sun spectrum with the accuracy up to 4 percents. The experimental specimen offered allows to estimate the reflection ability of the object metal surfaces under high temperature and at a far distance from the information receiver.
