All object temperature above absolute zero (- 273 ℃) emits infrared radiation. Infrared imaging sensor will translate the infrared radiation into visible image information to the human eyes. Infrared imaging technology covers material science, sensor technology, IC technology, infrared optics and image processing algorithm, etc. The key device of infrared imaging is infrared sensor, which using the physical effect of infrared radiation interacting with matter to detect infrared radiation.
Atmosphere and smoke absorbing visible light and near infrared, but is transparent for 3 ~ 5 micron and 8 ~ 14 micron infrared wavelength. These two bands are referred to as the atmosphere "window" of infrared radiation, through which distant objects can be clearly observed even in night or smoke environment. As a result of above characteristic, the infrared imaging technology is also used in driving assistant at night, security monitoring and traffic monitoring fields.
Unlike visible light image, infrared radiation energy is directly relating to temperature of object surface. Infrared imaging represents temperature distribution of objects. This characteristic makes it widely used in non-contact temperature measurement application, including building energy efficiency assessment, industrial temperature measurement, power detection, disease control and prevention, and health care fields.
With the development of the uncooled infrared focal plane detector technology towards to miniaturization and multi-function direction, the application of infrared imaging technology is more and more close to people's lives. In the future, we will benefit from infrared technology as long as taking out mobile phone, such as outdoor travel at night, discovering fire hazard, and the human body detection, etc. Infrared imaging technology extends the person's vision, will be widely used in our life.
Typical image rendering our infrared imaging products are as follows:
