Tracing Back the Infrared Roots

The history of infrared technology dates back to the 19th century, when British astronomer Sir William Herschel discovered infrared radiation. Since then, this invisible part of the light spectrum has been utilized in various applications, primarily within the military and scientific communities.

During World War II, for example, infrared technology was used to detect enemy aircraft and submarines. In the decades following the war, advancements in IR technology made it an invaluable tool in the fields of astronomy, medicine, and environmental science.

Infrared Technology Here and Now

Today, the applications of infrared technology have expanded beyond the realms of science and defense. From smartphones to home security systems, IR technology is increasingly becoming a part of our everyday lives.

In smartphones, IR technology is used in features like face recognition and augmented reality. Home security systems, on the other hand, use IR sensors to detect motion and heat, allowing them to work even in complete darkness.

Pricing and Market Impact

The increasing consumer demand for IR technology has led to a significant reduction in its market price. For instance, an infrared security camera that would have cost several thousand dollars a decade ago can now be purchased for less than $100.

As a result, the global infrared detector market is expected to grow at a compound annual growth rate (CAGR) of 9.69% from 2021 to 2026, according to a report from Mordor Intelligence.

Research-Backed Claims

A recent study published in the Journal of Infrared, Millimeter, and Terahertz Waves confirms the safety and efficacy of using IR technology in various consumer applications. The study found that IR sensors are highly accurate and reliable, making them a preferred choice for applications like home security and smartphone features.

Keeping it Simple: Infrared in Our Daily Lives

Despite its scientific complexity, the working of infrared technology is quite simple. Infrared devices emit IR radiation, which is reflected off objects and returned to the device. The device then measures the time it took for the radiation to return, determining the distance of the object.

This simple yet effective process is what allows your smartphone to recognize your face, your TV remote to change channels, and your home security system to detect potential intruders.

As we delve further into the digital age, the applications of infrared technology in the consumer market will only continue to expand. It’s not just about what we can see—it’s also about what we can’t see, and infrared technology is helping us see the invisible.
