We use infrared radiation in many ways, including thermal imaging cameras, remote controls, fiber optic cables, infrared astronomy, and meteorology.
What is common infrared used for?
Infrared sensing
One of the most useful applications of the IR spectrum is in sensing and detection. All objects on Earth emit IR radiation in the form of heat. This can be detected by electronic sensors, such as those used in night vision goggles and infrared cameras.
What are examples of infrared?
The heat that we feel from sunlight, a fire, a radiator or a warm sidewalk is infrared.
How is infrared used in medicine?
The therapeutic effects of heat
Infrared radiation can promote local blood circulation and reduce muscle tension. Examples of traditional medical applications of infrared radiation include the relief of muscle pain and tension, as well as the treatment of autoimmune diseases or wound-healing disorders.
What electronics use infrared?
The sun, light bulbs, fluorescent bulbs, fireplaces and in fact, anything that radiates heat, also radiates infrared light. Using IR for a remote now sounds like a recipe for disaster right? Wrong.
Is infrared helpful or harmful?
Invisible radiation, such as the radiation from infrared heating, is harmless for the human body provided the power, distance and duration are appropriate.
What is red light therapy used for?
Red light therapy (RLT) is a treatment that uses low wavelength red light to reportedly improve your skin’s appearance, such as reducing wrinkles, scars, redness and acne. It’s also touted to treat other medical conditions.
Why do TV remotes use infrared?
An IR remote (also called a transmitter) uses light to carry signals from the remote to the device it controls. It emits pulses of invisible infrared light that correspond to specific binary codes. These codes represent commands, such as power on, volume up, or channel down.
