How Does An IR Camera Work?

1. How Does an IR Camera Work? thermoelite.ca/how-does-an-ir-camera-work 416 An Infrared (IR) camera is an image-capturing device that images infrared radiation. The cameras show captures images of different colors based on their surface temperature. IR Cameras are used to conduct inspections in homes and factories, to establish whether certain structures and systems are in good condition. IR cameras work based on heat differences on the surfaces of different objects. They have become important devices as far as the inspection of various systems and structures is concerned. In the sections below, we are going to explore how IR cameras work, and the various types available. We will also discuss their benefits over other methods of inspections. IR Camera Operation IR cameras are built just like any other camera. You’d be forgiven if you unknowingly bought an IR camera to take photos in your next vacation. However, these cameras produce thermal images of different objects and surfaces. All objects and surfaces have the capacity to emit and absorb light depending on their surroundings. However, different surfaces emit and absorb light at different rates. As such, different objects or surfaces with have different levels of infrared radiation. As mentioned above, the working of an IR camera is majorly banked on temperature changes. As heat moves, it causes IR radiation, which the camera captures. Different levels of IR radiation are depicted as colors on the camera’s screen. The result is images 1/2

IR cameras, unlike ordinary cameras, can capture images of objects that are not visible to the naked eye. Infrared cameras are non-contact and quite easy to use. You focus on the object you want to image, just like you would with an ordinary camera, and then press the shutter button to capture images. Some IR cameras capture light images alongside thermal images as well. This makes it easy to analyze the images and draw conclusions. 2/2
