| Summary: | 碩士 === 國立彰化師範大學 === 顯示技術研究所 === 98 === Temperature in human life which is extremely important indicator of the body temperature represents a life management activities, and health. However, there are many ways to measure body temperature, for efficiency, hygiene and safety, The non-contact infrared thermometers are widely used in the temperature measurement solutions, and the most commonly used of which the amount of temperature measurement, But at present the amount of temperature
measurement errors are often large, So we need to contact the measurement to improve their problems.
In this study, we designed using two thermistor in the infra-red temperature gun in terms of hardware, to circuit testing and calibration in temperature compensation, and thus enhance of the fast measurement, to increase the accuracy of temperature measurement. Because the infrared
temperature gun body, it will have a greater change in temperature of the environment from A to B or the temperature by hand, Therefore, the body temperature gun to adapt to the temperature after some time, and then it get an
accurate reading, so we designed a temperature compensation, to modify the temperature.
In addition, we offer a potential new method of rapid temperature measurement, temperature, instead of using iris forehead temperature. We had two on the temperature and the temperature stability of the experimental application of iris infrared sensing, we carried out mathematical operations data, the correlation coefficient obtained to study the correlation between the two, it is more likely to know the temperature stability of the iris with body temperatures. Based on the results, it shows a high correlation between the two rendered temperature and iris in the eardrum temperature, up to 0.926. Therefore, we propose a reference measurement temperature measurements in the iris to replace the amount of temperature.
