1. What is thermal sensitivity?
Thermal Sensitivity, also named NETD (Noise Equivalent Temperature Difference), is a key parameter for evaluating medium wave (MWIR) and long wave (LWIR) thermal imaging cameras. It is directly related to the clarity measured by the thermal imager. It is a numerical value representing the signal-to-noise ratio of the temperature difference and measured in milliKelvins (mK). The smaller the thermal sensitivity value, the higher the sensitivity and the clearer the image.
2. What are the applications of thermal imaging?
Temperature measurement and all-weather imaging are two basic
functions of infrared thermal imaging technology. Products
developed based on these two technologies are widely used in
security & monitoring, UAV payloads, industrial inspection,
firefighting, predictive maintenance, ADAS, epidemic prevention,
AIoT etc.
