Temperature Resolution

Temperature resolution is the smallest temperature difference that can be detected and distinguished by an infrared sensor or thermal imaging system. It’s an important factor in determining the sensor’s ability to provide detailed and accurate thermal insights. A good temperature resolution enables the detection of small temperature variations.

Several factors influence temperature resolution, including the sensitivity of the infrared detector, the quality of the optical system, and the signal-processing capabilities of the device.

It’s important to note that temperature resolution is different from the Noise Equivalent Temperature Difference (NETD), which represents the smallest temperature difference that produces a signal equal to the noise level of the system. While temperature resolution refers to the smallest digital step size, NETD value takes into account the noise of thermal sensing systems.

However, to adequately detect small temperature anomalies, the NETD value should be 2 to 3 times smaller than the temperature variation being monitored.
