    摘要: Method and apparatus for measuring a surface temperature of an object body (12), by calculating a temperature at each local portion of an image of the object body, on the basis of a radiant intensity ratio at each pair of corresponding local portions of a first and a second image which are obtained by respective first and second photosensitive areas (B 1 , B 2 ) of an image detector (32; 32'), which detect respective radiations having respective first and second wavelengths selected from a light emitted from the surface of the body, wherein the image detector is constructed such that each pair of mutually corresponding two photosensitive elements in the respective first and second photosensitive areas, which corresponds to each pair of mutually corresponding two local portions of the first and second images, has a percentage of difference in light sensitivity of not higher than 0.25%.
