What are the effects of thermography on human body temperature
measurement?
Any object whose temperature is higher than absolute zero (- 273.15
℃) continuously emits infrared radiation (thermal radiation).
Infrared radiation is a kind of electromagnetic wave, the
wavelength range is 0.7um ~ 1000um, which can not be seen by human
eyes, and the wavelength of external radiation is different at
different temperatures. After absorbing infrared radiation, the
temperature of the thermal sensitive material will rise. The
thermal imaging camera calculates the corresponding temperature
information according to the corresponding temperature rise.
For human body, the body temperature is relatively constant, and
armpit temperature is 34.7 ℃ ~ 37.3 ℃. But the temperature of human
face, due to the influence of sweating or wind blowing, will have a
certain change. The thermal imaging camera measures temperature by
detecting thermal radiation of human surface, and the temperature
measurement results will fluctuate with sweating or wind blowing.
In this case, it is recommended to retest. At present, the optimal
installation environment is indoor, and it not recommended to
install itoutdoors
(including the area directly connected to the indoor and outdoor).
According to above principle, this is because the outdoor
environment is easy to be affected by the external environment on
the body surface temperature, resulting in a large deviation
between the body surface temperature and the real body temperature.
