Thermal Imaging Principles
The principle of infrared thermography is based upon the physical phenomenon, any body of a temperature above absolute zero, -273.15 °C / -459.67°F, emits electromagnetic radiation. Electromagnetic radiation that has both electric and magnetic fields that travels in waves. Electromagnetic radiation come from natural and man-made sources. Electromagnetic radiation can vary in strength from low energy to high energy. It includes radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays.
The available facts, in the form of non competitive video links, is brought to you by Infraspection Institute. The leading institute and instructor in thermography/thermal imaging. The first YouTube video , in a series that follow, will hopefully help individuals understand the principles of thermography.
What is Thermography? THERMOGRAPHY.
What are the applications for thermography? Thermography Applications.
How are Thermographic Inspections Performed? The Concept; All earth bound objects emit infrared radiation.
Who should perform an infrared inspection? An infrared inspection should be performed by individuals taught to interpret infrared theory and the other actions.
Why is training important? Training is the most important in the infrared inspection program that company offers. Advancements and technology has made infrared equipment user friendly, however, thermography is not a point and shoot technology.
Is all training equal? No. There are many courses. There are (3) Main Level courses, as well as individual course applicable to 'specific content.' Moreover, manufacturers offer course that specifically cover only their equipment. There are Live Open Book Courses, as well as Distance Learning.

Thermal Imaging
In brief; thermal Imaging is a method to improve the visibility of objects by detecting an/the objects' infrared radiation signature/s, heat, and creating an visible image based upon that information. Infrared energy emitted by an object is known as its, heat signature. In practice, the hotter an object is, the more radiation it emits. A heat sensor/detector is used to detect heat signatures, a thermal camera, and capable of detecting minuet differences in an object's temperature in the scene, creating an electronic image, through-software, based upon the information about those temperature differences.
A thermographic camera, or thermal imaging camera, is a device that forms an image using infrared radiation, and is similar to, but not exactly alike, as a common camera that forms an image using visible light. Instead of visible light, nanometre range between 400–700, of a typical visible light camera, infrared cameras operate in longer, with the electromagnetic spectrum between (roughly 9,000–14,000 nanometers or 9–14 µm). There use, thermal imaging, is referred to as thermography, The operator, a thermographer.

Advantages Of Infrared Thermal Imaging
The Advantages of Infrared Thermal Imaging is broad. It is common for materials and systems to wear or fail altogether over time. Nothing lasts forever. The life of a system or the common components in your home that protect you from the elements is directly related to how often they are inspected, and how quickly small problems are identified and repaired. By inspecting and maintaining operating systems & components on a pre- scheduled bases just makes makes financial sense.
