The reason of why the thermal camera smartphone gained favor from many users around the world is its practicality and portability. In this post, we’ll take you to learn about thermal imaging.
Thermal imaging is a technology that allows us to see and measure the heat emitted by an object or a living organism. This technology is based on the principle that all objects emit infrared radiation, which is invisible to the naked eye but can be detected by a thermal camera.
Thermal imaging cameras work by detecting the infrared radiation emitted by objects and converting it into an image that we can see. The cameras use a special lens to focus the infrared radiation onto a detector array, which is made up of thousands of tiny sensors. Each sensor measures the temperature of the object it is looking at and generates a pixel in the image based on that temperature.
The resulting image shows different colors or shades of gray, depending on the temperature of each pixel. Warmer objects appear as brighter colors, while cooler objects appear as darker colors. This allows us to see the temperature differences between different parts of an object or living organism.
There are two main types of thermal imaging cameras: uncooled and cooled. Uncooled cameras use a microbolometer detector array, which is made up of tiny elements that change their electrical resistance when they are exposed to infrared radiation. Cooled cameras use a more sensitive detector material, such as mercury cadmium telluride (MCT), and are cooled to very low temperatures to reduce electronic noise and improve sensitivity.
Thermal imaging has many practical applications in fields such as medicine, building inspection, law enforcement, military surveillance, and agriculture. For example, doctors can use thermal imaging to detect tumors or other abnormalities in the body that may not be visible with other imaging techniques. Building inspectors can use thermal camera to detect heat loss or water damage in buildings. Law enforcement agencies can use thermal imaging to track suspects at night or in low-light conditions. And military personnel can use thermal imaging to detect enemy activity or locate targets.
