NETD is a widely used performance parameter that characterizes the sensitivity of thermal imaging sensors. NETD is the amount of incident signal temperature that would be needed to match the internal noise of the detector (such that the signal-to-noise ratio is equal to one). Essentially, it specifies the minimum detectable temperature difference. Typically NETD is expressed in units of Kelvin (K). …

1• Thermopile and Local Die Temperature Sensor that measures the temperature of an object without – NETD: 90 mK contacting the object. The integrated thermopile – Responsivity: 9 V/W absorbs the infrared energy emitted from the object in – Sensor Noise: 300 nVrms the sensor field of view. The thermopile voltage is
hollow space. Our thermopile detectors use materials that have a large Seebeck coefficient (thermal electromotive force) and are easily formed by the semiconductor process. When infrared light enters a thermopile detector having the above mentioned structure, the hot junction on the membrane heats up and produces a temperature
The information in the Table 1 are extracted from publications about microbolometer and thermopile sensors [8] - [13] . At first sight, the microbolometric sensor appears to be an attractive choice. Compared with the thermopile, its detectivity is higher; it has a high performance NETD and a significantly better response time. Obviously, these ...
