Ways to Improve Temperature Measurement Accuracy of InfraScope Thermal Mapper

Abstract

In this paper we discuss the ways to improve the accuracy of InfraScope Thermal Mapper. We demonstrate the theory about space resolution and how it influences the temperature measurement using InfraScope Thermal Mapper. Then a way to enhance the accuracy by choosing the space resolution adequately is presented. Some experiments are designed and the results prove the way is effective. Then we study on the basic structures and work procedures of this instrument, combining with theory analysis we conclude an efficient emissivity measurement method. Following which we can measure emissivity at a single temperature. Then we analyze errors brought in by this method in emissivity calculation procedure, deliberately propose ways to improve on the measurement accuracy. At last, we verify the improvement by precise experiments.
