Non-contact thermography

Okay kiddo, do you remember playing hide and seek and how you could tell where your friends were hiding by feeling their body warmth when you got close? That's kind of like what non-contact thermography does, except it can detect heat without even touching the object.

Non-contact thermography is a way of measuring the temperature of things from a distance. It uses special cameras that can detect infrared radiation, which is a type of energy that all objects emit. This radiation is invisible to the human eye, but the cameras can pick it up and turn it into an image that scientists and doctors can use to see how hot something is.

For example, doctors can use non-contact thermography to see if someone has a fever by pointing the camera at their forehead. The camera picks up the infrared radiation coming from the forehead, which is hotter than the surrounding skin, and creates an image showing where the heat is coming from.

Scientists can also use non-contact thermography to study things like volcanoes, where it can be dangerous to get too close. By using the cameras to measure the temperature of the lava from a safe distance, they can learn more about how the volcano is behaving.

So, non-contact thermography is a way of measuring temperature from a distance using special cameras that can detect infrared radiation. It's kind of like playing hide and seek with heat!
