How Thermal Imaging Cameras Work

An infrared camera is a device that converts invisible infrared rays faculty of different temperatures into images.

The working principle of the infrared thermal imager is to convert the infrared rays emitted by the object into visible black and white images through the infrared camera. The difference in the relative temperature between the objects is reflected on the black and white image obtained by the detection as different gray levels, and the object temperature is relatively high. Bright, darker on the contrary, with a resolution of 0.4 degrees Celsius. For example, using an infrared camera to observe a glass of water at 60 degrees Celsius is very bright at room temperature, and it is very dark at 25 degrees Celsius.

The good resolution of the infrared camera can not only judge the temperature, but also can know the location of the fire source, the fire combustion situation, and the flow direction of the high-temperature combustible gas. In addition, the infrared camera will play its role in measuring temperature, penetrating smoke and imaging.

Based on its good features, the use of infrared thermal imaging cameras is also quite extensive: it is possible to search for rescue personnel and find fire sources at disaster sites. Help combatants control the direction of water jets and reduce water loss. Help rescue workers find potential dangers. Observe heat waves in tank fires and predict boiling and splashing.
