ABSTRACT:
A radiant-energy temperature measuring apparatus of a scanning type having a linear array of light-sensitive elements which generate photoelectric signals corresponding to respective amounts of radiant energy produced at different points of an object and vicinities thereof on a straight line corresponding to the above linear array, and further having a device for determining a temperature of the object at desired one of its different points, based on the photoelectric signal generated by one of the light-sensitive elements which optically matches the desired one point of the object. The apparatus includes an edge detector for detecting an edge of the object, based on the photoelectric signals generated by the light-sensitive elements, and a selector for selecting the desired one point of the object, by designating a number of the light-sensitive elements as counted from the element corresponding to the detected edge of the object, to the element which corresponds to the above-indicated desired one point. The selector applies to the temperature determining device the photoelectric signal from the light-sensitive element corresponding to the selected point.
