Can thermal imaging detect farts?

Thermal imaging cameras cannot detect the gas that comes out of a human’s body. This is so because the gas is very close to room temperature and the gas is not dense enough to register on the camera. Basically, if you were able to detect a gas coming out of a human body, you would be able to detect a human and animal’s breathing out, which is not the case. This leads us to an answer to the question that is a definite no. But why exactly doesn’t a thermal imaging device detect a gas that is close to room temperature. Keep on reading to dig deeper into this question and find out more about it.

Related Questions:

  1. Can thermal imaging see through smoke? – Because most thermal imaging devices see heat and rely on infrared wavelengths and not light, thermal night vision devices like FLIR BTS for example can definitely see through different thickness of smoke, fog and even dust as well as seeing through the night. Infrared imagers still have a lot of different uses in daylight and can even see through the thickness of the smoke coming from a smoke grenade.
  2. Can thermal night vision goggles see through fog? – Thermal night vision goggles detect thermal radiation and do not need any source of illumination for them to work perfectly. They produce their own image even in the darkest of nights and can clearly see through light fog, rain, smoke and even heavy snowfall. 
  3. What is better night vision or thermal? – To be able to decide what is better you have to take into consideration the environment that the said device from each type will be used in. Thermal scopes detect all kind of temperature radiation and do not need visible ambient light sources from starlight and moonlight to offer their user an image. They work as their own flashlights for night vision but are completely invisible to the human eye. On the other hand, night vision devices cannot be used in brighter light because the intensifier tube can be permanently damaged. If there are low-light conditions with present ambient light like starlight or moonlight, for this condition a night vision would be better and vice-versa.
