History of Infrared
Infrared cameras, also known as thermal imagers or forward looking infrared (FLIR), were originally developed for military use during the Korean War to further enhance night vision capabilities. Thermal infrared cameras quickly found applications in public safety and then slowly migrated into commercial fields where they are used as tools to conduct electrical inspections and home energy audits.
- Military Applications
Night vision optics are used extensively by the United States armed forces and have been incorporated into aircrafts and sea and land vehicles. Ground forces use a hand held ir camera for general theatre scanning and a thermal imaging scope for target acquisition.
- Thermography Definition
Thermography is a technique for detecting and measuring variations in emitted heat and transforming them into visible signals that can be recorded photographically.
What is Infrared Light?Infrared light (IR) is electromagnetic radiation with a wavelength between 0.7 and 300 micrometers, which makes it longer than visible light but shorter than microwaves.
The articles section of this web site discusses topics in thermal imaging discuss basic infrared theory and thermal imaging terms like emissivity.
Infrared Uses Overview
- Modern Applications of IR Technology
This amazing infrared technology has many diverse uses in everyday life. Advanced IR optics sensors with sophisticated software interfaces and increased affordability continue to enhance the versatility of thermal infrared cameras which are now commonly used for predictive electric maintenance, research and development, home energy audits, and home inspections.
- Predictive Maintenance
In all electrical or mechanical systems, excessive heat is a reliable predictor of future breakdowns. Professional, comprehensive infrared inspections can reduce downtime, prevent disastrous failures, and most importantly, save lives and money.
- Electric Panel Inspection
This series of images shows the tremendous amount of heat generated and emitted by different overloaded circuits. Diagnosing and repairing this type of potentially hazardous resistance of electrical flow can prevent costly and life threatening structural fires.
The origin of conductor, insulation, and component electrical problems can be traced to poor connections by a trained and certified thermographer using an infrared camera. The forging of friction causing resistance in mechanical systems can also be found this way.
Home Energy Audit
Homeowners and residential contractors use infrared energy audits to diagnose and resolve problems and improve home energy efficiency. Since infrared cameras display heat as a visual image, inspectors can take pictures of home energy losses.
