Abstract
A radiant-temperature measurement device includes a time-based data measurement unit for acquiring, based on an intensity of first light, a first data value during a first measuring interval in a first intensity duration, and a second data value during a second measuring interval in a second intensity duration. The time-based data measurement unit is also for acquiring, based on an intensity of second light, a third data value in a first wavelength band, and a fourth data value in a second wavelength band, during the first measuring interval, and a fifth data value in the first wavelength band, and a sixth data value in the second wavelength band, during the second measuring interval. The radiant-temperature measurement device also includes a temperature calculation unit for calculating, based on the first, second, third, fourth, fifth, and sixth data values, a temperature of a light source at its light-emitting end.
