Can thermal imaging see through the blind box

In nature, any object whose temperature is higher than absolute zero (-273. 15℃) will radiate infrared energy (heat). Thermal imaging technology can transform invisible infrared radiation emitted by objects into visible thermal images. Thermal imaging technology can break through night barriers, rain and fog, strong light, smog and other harsh conditions, and can work all day.

But generally speaking, the blind box has a certain thickness, which can basically block the infrared radiation on the other side, so generally speaking, thermal imaging can not see through the blind box. If there is a temperature difference between the objects in the blind box, thermal imaging can detect the heat of the blind box.

Thermal imaging has many advantages that visible light does not have. Its main functions are temperature measurement and night vision, which are widely used in industrial temperature measurement, fire safety, medical examination and scientific research.
