1. Meteorological forecast
In the field of meteorological monitoring, because there are Fengyun series meteorological satellites and ocean series satellites that monitor day and night and send satellite cloud images, typhoon prediction is becoming more and more accurate. In particular, the infrared detector component on the satellite is made into a remote sensing instrument and placed on the satellite, so that various imaging can be observed.
Ii. Military reconnaissance
Infrared detection has the characteristics of good environmental adaptability, good concealment, strong anti-interference ability, can identify camouflaging targets to a certain extent, and the equipment is small in size, light in weight, low power consumption, and is widely used in the military in infrared night vision, infrared reconnaissance and infrared guidance.
Three, airport security
In today's extremely convenient transportation, before taking the subway, trains, and planes, they need to go through the security check when entering the station. Through the security check instrument, the staff can check whether they carry prohibited items without opening the package, so as to escort the safety of each passenger.
At present, scientists are working to expand the detector's band to terahertz. Because terahertz waves have a certain transmission depth, they have important applications in imaging, such as airport security, national defense, and gutter oil detection. In front of the terahertz security screen, the terrorists' hidden weapons were revealed.
Iv. Medical examination
In the medical industry, infrared detectors can be found everywhere, and the most common one is the infrared thermal imager. Based on the principle of infrared radiation, the infrared thermal imager takes the human body as the radiation source and adopts infrared detectors to capture the infrared radiation energy emitted by the object, and convert the infrared radiation emitted by the surface of space objects into visible and quantifiable pseudo-images. The light color indicates high temperature and dark color indicates low temperature, which makes the infrared heat map more intuitive and easy to read, and is widely used in clinical diagnosis involving many fields.
5. Environmental monitoring
The epidemic suddenly hit in early 2020, in order to better control and prevention, whether it is individuals and families, or communities, stations, hospitals and other places are in urgent need of thermometers to screen patients with fever, so the demand for thermometers has increased. The non-contact infrared thermometer calculates the surface temperature of the object by measuring the intensity of the infrared radiation emitted by the target, and does not contact the object during the whole process.
6. Ground-based imaging
The larger the size of the infrared detector, the more clearly you can see, the larger is the number of pixels, and the largest is 64 million pixels made by the United States.
