Abstract
A first radiance meter is directed toward an object to be measured, radiance is measured through a space where dust is present with the use of at least two wavelengths by the first radiance meter, second radiance meters which are equal in number to one or more objects having temperatures different from that of the object to be measured are directed toward the objects, radiances are measured through the space with the use of at least two wavelengths by the second radiance meters respectively, and a temperature of the object to be measured, a temperature of the dust, and concentration of the dust are measured from the radiances measured by the first radiance meter and the second radiance meters.
Claims17
A method of calculating a temperature of an object to be measured, a temperature of dust, and a concentration of the dust, comprising:
- directing a first radiance meter toward the object to be measured and measuring a radiance of the object to be measured through a space where the dust is present using at least two wavelengths by the first radiance meter;
- directing second radiance meters, which are equal in number to one or more objects having temperatures different from that of the object to be measured, toward the one or more objects having temperatures different from that of the object to be measured, and measuring radiances of the one or more objects having temperatures different from that of the object to be measured through the space with the use of at least two wavelengths by the second radiance meters respectively;
- and
- calculating the temperature of the object to be measured, the temperature of the dust, and the concentration of the dust from the radiances of the object to be measured and the one or more objects having temperatures different from that of the object to be measured that were measured by the first radiance meter and the second radiance meters.
