What is Thermal Imaging? Thermal Imaging, as the name suggests, involves imaging an object’s heat as it radiates off the object’s surface. Thermal Imaging is done using thermal cameras. They are also known as infra-red camera’s. These cameras can capture infra-red rays radiating off an object, and depict them as various colors depending on the amount of heat the object is radiating.
Any object can absorb or emit heat. Different surfaces absorb or emit heat at different rates. As such, it becomes easy to image different types of surfaces, since their thermal images will be clearly defined by different colors. For instance, cold surfaces are often depicted on the thermal image by shades of either blue, green, or purple. Warm surfaces will appear yellow, orange, or red. Infrared cameras are a special type of camera that can capture infrared rays. As mentioned earlier, all objects emit infrared rays. Infrared cameras capture these rays and depict them as different colors on a screen depending on their intensity. Modern infrared cameras can measure the intensity of the rays and hence the temperature of the surface being imaged. www.thermoelite.ca
