Abstract

Based on the development of infrared thermometry all over the world, a problem has been pointed out. Whenever infrared thermometer has been used in measuring temperature, the field of full vision of target must be considered. Or else there will be a mistake. In the thesis, base on the theory of infrared thermometer, we analyze the reasons of the error. And we also deduce the theory equation of partial vision temperature measurement about infrared thermometry. In the process of deduction, because of the other influences are not considered; so we get the approximate equation of partial vision temperature measurement, based on measurement value we draw a compensatory curve to compensate the equation of infrared thermometry. The curve has reflected the compensating effect well. In the end, we analyze the reasons of error. We draw a conclusion that this method of partial vision temperature measurement is feasible. We discuss the error which caused by distance and get a feasible method to correct the error.
