| description | This paper presents a novel method of non-contact infrared thermometry optimized for remote monitoring in cold climates. The method consists of selectively heating the optics of the instrument in order to prevent ice forming on the lens and blocking infrared energy. A self-calibration method is used to remove the errors caused by thermal shock when the heaters are cycled. Applications for this instrument include the monitoring of roads and railways to detect ice as well as long-term environmental studies. The self-calibration technique is shown to maintain an accuracy of ±1 °C in ambient temperatures as low as −20 °C. This compares with errors of over 20 °C in a conventional infrared thermometer. |
