Abstract
A temperature measurement device is provided with: light collection means; extraction means; optical intensity calculation means; and temperature measurement means. The light collection means collects the emission spectrum of a measurement subject. The extraction means extracts light having the wavelength of the atomic spectral lines and light having a wavelength in a wavelength region where there are no atomic spectral lines, from the emission spectrum collected by the aforementioned light collection means. The optical intensity calculation means calculates the optical intensities of the light extracted by the aforementioned extraction means. The temperature measurement means calculates the temperature of the aforementioned measurement subject, based on the intensities of the beams calculated by the aforementioned optical intensity calculation means.
