Infrared rays are a type of electromagnetic radiation that falls within the non-visible portion of the electromagnetic spectrum. They have longer wavelengths than visible light and are commonly emitted and reflected by objects in the form of heat. Infrared rays play a crucial role in thermal imaging technology, as they allow for the detection and visualization of heat patterns in different objects and environments. This technology uses specialised cameras to capture and convert these infrared rays into visible images that can be analysed and interpreted for various applications. Understanding what infrared rays are is essential in comprehending the principles behind thermal imaging technology’s functionality.
Infrared rays were first discovered by the astronomer Sir William Herschel in 1800. While conducting experiments on the temperature variation within the different colours of the visible spectrum, he noticed an increase in temperature beyond the red end of the spectrum. This led to the discovery of infrared radiation and laid the groundwork for the development of thermal imaging technology. Since then, the applications of infrared rays and thermal imaging have expanded across various fields, revolutionising industries such as building inspections, electrical inspections, medical diagnosis, surveillance and security, and wildlife and environmental monitoring.
Objects emit and reflect infrared radiation through a process known as thermal radiation. When an object’s temperature exceeds absolute zero, it emits electromagnetic radiation in the form of infrared waves. This emission occurs due to the vibrations and movements of the atoms and molecules within the object. The amount and wavelength of the emitted radiation depend on the object’s temperature and surface properties. When infrared radiation interacts with another object, it can either be absorbed, transmitted or reflected based on the properties of the object. Understanding how objects emit and reflect infrared radiation is crucial for accurately interpreting thermal imaging data. This knowledge is essential for the effective utilization and interpretation of thermal imaging technology.
