ABSTRACT:
A temperature distribution measuring instrument comprises an outer cylinder having slits, an inner cylinder having a slit and a sensor array, arranged at the center of the cylinder, for detecting infrared rays passing through these slits. Each of the slits of the outer cylinder is changed in width according to its angle from a plane passing the center axis of the outer cylinder and the center of an object to be measured to equalize the measurement areas of the object and the rotation speed of the inner cylinder is changed to equalize the input times of infrared rays input from the object into the slits of the outer cylinder.
