InfraredTV
Infrared TV is a sister site of American Infrared Consultants LLC and our YouTube site. Created in 2006, InfraredTV is dedicated to sharing all things video-related to infrared and thermography. Check out our YouTube page for our personal videos, scans, and interviews with local news stations.
What is Infrared?
Infrared is electromagnetic radiation with a wavelength between 0.7 and 300 micrometres, which equates to a frequency range between approximately 1 and 430 THz. Infrared wavelength is longer (with a lower frequency) than that of visible light, but the wavelength is shorter (with higher frequency) than that of terahertz radiation microwaves.
In lamens terms, Infrared is light that we cannot see, but our bodies can detect as heat. It is part of the electromagnetic spectrum that includes radio waves, X-rays and visible light. All of these forms of energy have a specific frequency. Infrared technology detects the temperature emitted from objects and their variations. Certain variations can determine if you have a water leak, an overheated electrical fuse, whether you have a fever and more. Thermographers use this technology in a variety of home and building applications to detect building envelope troubles as well as minor problems such as locating termite nests and missing insulation.
Infrared imaging is used extensively for military and civilian purposes. Military applications include target acquisition, surveillance, night vision, homing and tracking. Non-military uses include thermal efficiency analysis, remote temperature sensing, short-ranged wireless communication, spectroscopy, and weather forecasting. Infrared has also been recently incorporated in energy audits, building and home inspections, and medical analysis. Astronomy-related infrared uses sensor-equipped telescopes to penetrate dusty regions of space, such as molecular clouds to detect planets. Infrared is soon expanding into the video game industry with the use of infrared sensors and remotes.
At the atomic level, infrared energy elicits vibrational modes in a molecule through a change in the dipole moment, making it a useful frequency range for study of these energy states for molecules of the proper symmetry. Infrared spectroscopy examines absorption and transmission of photons in the infrared energy range, based on their frequency and intensity.
