The result is a thermal image that showcases varying temperatures, represented in color gradients—typically from cold (blue) to hot (red).
Unlike standard cameras that capture visible light, thermal cameras detect infrared radiation, which is invisible to the human eye. This ability to see temperature differences opens up a wide range of practical applications, even for everyday users.
How Do Compact Thermal Imaging Cameras Work?
Thermal imaging cameras use infrared sensors to capture the heat energy emitted by objects. These sensors detect wavelengths of infrared radiation and convert them into a visual image. The more heat an object gives off, the brighter or more intense its color will appear in the thermal image.
The process generally involves the following steps:
Detection of Infrared Radiation
The camera’s sensor detects infrared radiation emitted by the objects in the environment. Every object with a temperature above absolute zero emits infrared radiation.
Conversion to Image
The detected infrared data is converted into an electronic signal, which is then processed by the camera.
Display of Thermal Image
The processed data is displayed on the camera’s screen, showing a thermal image with temperature variations represented by different colors.
Analysis
The user can analyze the thermal image to identify temperature anomalies, which can be useful for a range of applications.
