In recent years, infrared imaging has been increasingly used in health and medical applications in addition to the usual microwave ultrasound and X-ray based imaging methods. Unlike other imaging technologies, infrared imaging is a passive method for detecting infrared energy emitted from living organisms. Therefore, no radiation is emitted to the living organism and there is no harm.

Infrared imaging is mainly used in diagnostic applications based on the determination of temperature distribution differences in the human body due to various reasons. For example, it has been widely used in the detection of infection and inflammatory conditions, burn and breast cancer cases, blood circulation system disorders, soft tissue injuries. In addition, it is used for sick passenger control at airports to prevent the spread of infectious diseases such as SARS. This method can easily meet the high resolution, high sensitivity and fast imaging requirements for diagnosis and diagnosis.
