“This temperature measuring device is equipped with a temperature detection means for detecting the temperature of the measuring object member by the intensity of the infrared ray from the measuring object member, a correction temperature measuring means for measuring the temperature of a facing member facing to the measuring object member or the temperature of the member whose temperature is changed correlatively with a temperature change of the facing member, and an operation means for correcting a detected temperature acquired by the temperature detection means by the correction temperature acquired by the correction temperature measuring means.”
In simple words, the temperature detected by CTD711 is only the one in front of the infrared sensor, and even if there are temperature changes in the surrounding (for example around the head while measuring the forehead) the measurement will recalculate itself and will not be affected by these surrounding changes, making the device extremely accurate even in changing environments.
