What is a Thermal Scanner and how does it work?


A thermal scanner is a device that produces a thermal image by recording body temperature. If the temperature of a person’s body is more than normal, then it also tells through the sound of a vape. This lets the officers know that this person is infected with the corona virus or any other similar disease.

The corona virus, which started in December 2019, has spread in more than 100 countries today and the number of people affected by it in the world has crossed 1.35 lakh and 5000 people have died. Many countries including India have stopped issuing visas to foreign travelers and those who are returning to India abroad are being subjected to thermal scanning at the airport to identify people affected by the virus.

The Indian Health Ministry has installed modern thermal scanners at 20 airports across the country, including Mumbai, Delhi, Kolkata, Ahmedabad, Mangalore, and Jaipur. So far, about 45 thousand people have been screened through thermal scanners installed at various airports across the country.

But now the question arises that what is this Thermal Scanner and how does it work? Let us know the answers to these questions through this article.

Thermal Scanner

Thermal scanner works through infrared thermography. Infrared thermography provides a digital image that shows the temperature pattern. This system can measure temperatures from 40 ° C to 500 ° C.

Along with changing the temperature of a person’s body, the color of the thermal image also changes. In addition to the pattern of colors in some devices, the body temperature is also written. Not only this, when a person’s body temperature is above normal, these scanners also give signals through beeps.

How Thermal Scanner Works?

Thermal scanners are mainly installed in crowded places like airports. When a person passes in front of this scanner, the virus present in the person’s body appears in the infrared photographs. The temperature of the body of people whose body reaches a high or dangerous level of viruses increases. Such people are separated from the crowd and they are investigated.

It is believed that infrared cameras may possibly be used to detect subjects such as fever, SARS symptoms, and avian influenza. It is worth noting here that the thermal imager measures the temperature of the skin and not the temperature inside the body. However, the accuracy of infrared systems; Quality of human, environment and equipment can also be affected.

It is thus clear that identifying people affected by Kovid 19 with the help of thermal scanners is a cheap, fast and reliable step. Hopefully, this vaccine will be discovered soon.
