Abstract: Provided is to perform an identification of a temperature and/or a material of a target object to be measured in a non-contact and simple manner. A relationship between a wavelength and an emissivity of thermal radiation such as infrared rays radiated from an object is determined by the material of the object. In the present invention, the identification is performed by using this. In other words, the object above can be achieved by comparing thermal radiation intensities at a plurality of wavelengths from the given object with a database in the present invention. The database is stored by measuring the thermal radiation intensities at the plurality of wavelengths and temperatures for a plurality of materials in advance. An external light source is not required, and the target to be measured itself is used as a thermal radiation light source in this measurement.

Abstract: The present invention makes it possible to represent or synthesize any odor by separating the odor into a combination of a relatively small number of odors, similarly to separating a color into three primary colors. Since the “primary odors” corresponding to the primary colors have not yet been ascertained, the present invention provides a feasible method and apparatus in which, instead of presetting such fixed primary odors, the separation, synthesis, and the like can be performed by selecting a subset of odors from among a set consisting of a plurality of odors which subset or odors enables approximation of other odors as much as possible by mixture.
