![]() Those pixels with a high, frame-rate capability become a high-definition image or video.Īn example of an IR image.The actual pixels are much smaller. Each individual IR detector in array grabs a minute frame, which is equivalent to one pixel. The IR detectors work together to form a single image. This is because IR photon energy takes longer to be acquired by the IR detector. The frame rate of an IR camera is lower than a typical imaging camera (the eye-detection is 32 frames per second). All the individual IR detectors work together to capture and build an image. For example, by using infrared-radiation imaging, it’s possible to measure body temperature, differentiate dead cells (versus live ones) in a living being, or even detect movement (say as a security measure against break-ins or theft, etc.).Īn IR camera has an array of thermal infrared sensors. This is where an IR camera comes in as it captures IR images, which can be useful in many ways. Sun and fire are sources of IR radiation.īy using IR, it’s possible to view the world within a heat dimension. When IR waves strike a surface, they vibrate and release energy. ![]() Though humans cannot see it, we can feel it in the form of heat. Infrared radiation (IR) is a part of the electromagnetic radiation spectrum. Infrared imaging or “heat vision” has been used in several industries, such as in the military, for surveillance and security, search and rescue, and for medical purposes, as well as in other sectors. A thermal camera works on the same principle as a conventional imaging camera - the only difference is in the detection of light/photons. ![]() Although infrared light is invisible to the naked eye, a thermal camera can detect it.Ī thermal camera is a non-contact device that picks up infrared energy (or heat) and then converts it into a visual image. Of course, humans cannot see heat directly, but objects do give off infrared radiation at a certain temperature. In this tutorial, we’ll learn the basics of “heat vision” and how to interface a thermal-imaging camera with Arduino.
