Because of black body radiation, any object will emit electromagnetic waves according to different temperatures, which is the principle that infrared thermal imaging can identify temperature.
Today it has a very wide range of applications, and people can monitor the temperature that occurs nearby in a particularly detailed manner. But do you know? Such widely used thermal imaging is not allowed to be installed on mobile phones. In fact, this has a lot to do with the effect of thermal imaging, which is very sensitive to temperature detection.
If it is installed on a mobile phone, it can further detect human behavior. For example, when a couple kisses passionately, their body parts will heat up. But if it is placed under the thermal imaging technology, it can be distinguished at a glance.
Even if you defecate anywhere on the street, you can clearly observe the flow of urine, which will bring some unnecessary troubles.
If thermal imaging is installed in the mobile phone, when several friends are chatting, someone farts silently. And if this scene happened to be recorded by a friend with a mobile phone, it would immediately become very embarrassing.
On the basis of thermal imaging, even dogs farting can be easily observed, so in order to protect people's privacy, thermal imaging must not be installed on mobile phones!
