Can infrared thermal imaging cameras measure human body temperature? What is the principle of infrared thermal imaging thermometers?

Infrared thermal imager can be used to detect human body temperature, with high speed and high efficiency. It is more suitable for large-scale body temperature screening in places with a large flow of people. Thermal image, different colors represent different temperatures of the object to be measured. By viewing the thermal image, you can observe the overall temperature distribution of the object to be measured. This detection method does not actively emit infrared radiation, but passively receives infrared radiation. It will cause harm to the human body, so you can use it with confidence. Let's take a look at the principle of infrared thermal imaging thermometer.

1. Can an infrared thermal imager measure human body temperature?

In railway stations, subways, airports, hospitals, supermarkets and other places with a large flow of people, using ordinary infrared thermometers to measure body temperature is slower and less efficient. Started using the infrared thermal imaging thermometer.

The infrared thermal imager can measure body temperature. Its detector can passively receive the infrared radiation of the measured object, convert it into a temperature value, and finally visually display the temperature distribution of the measured object, with non-contact measurement. , temperature visualization, large area measurement, avoidance of missed detection and other characteristics, and no harm to the human body, so it is widely used in large-scale body temperature screening.

2. What is the principle of infrared thermal imaging thermometer

Infrared thermal imaging thermometer is an infrared thermal imaging camera used to measure temperature. It can measure the body temperature of people entering and leaving a large area. It is very practical. Many friends do not know much about the working principle of infrared thermal imaging cameras. Let me introduce to you:

The working principle of an infrared thermal imager is: "any object above absolute zero emits infrared radiation", using an infrared detector and an optical imaging objective lens to receive the infrared radiation energy distribution pattern of the measured target and reflect it to the infrared detector This thermal image corresponds to the thermal distribution field on the surface of the object, and different colors represent different temperatures of the object to be measured. By viewing the thermal image, the entire object to be measured can be observed. Temperature distribution, study the heating situation of the target, so as to judge the next work.

3. Is temperature measurement by infrared thermal imager harmful to the human body?

no.

The temperature measurement principle of the infrared thermal imager is to passively receive the infrared radiation emitted by the object to image and measure the temperature. It does not actively emit infrared rays. Therefore, measuring the body temperature with the infrared thermal imager will not cause harm to the human body.
