Application fields of infrared sensors

Infrared sensors are often used for non-contact temperature measurement, gas composition analysis and non-destructive testing, and are widely used in fields such as medicine, military, space technology, and environmental engineering. For example, the use of infrared sensors to measure the temperature of the human body's surface temperature at a long distance can find out the parts with abnormal temperature, and timely diagnose and treat diseases (see thermal imaging cameras); use the infrared sensors on artificial satellites to monitor the earth's clouds, which can be realized Wide-range weather forecast; infrared sensors can be used to detect the overheating of the running engine on the aircraft, etc.

Telescopes with infrared sensors can be used for military operations, woodland warfare to detect enemies in dense forests, and urban warfare to detect enemies behind walls. Infrared sensors are used to measure the surface temperature of the human body to know where the enemy is.
