Abstract

PURPOSE:To accurately measure temperature from infrared rays by providing two reference heating sources within the device, obtaining the differences between the two reference voltages from these and adjusting the total gains of various systems so that the ratio of the differences between these differences and two reference temperatures becomes always constant.
