small area array thermopile detector

Miniature Thermopiles - Thermopiles

The thermopile is a thermal detector that is based on the Seebeck effect. Its predecessor was the thermocouple, which consisted of a junction between two metal wires with different thermoelectric voltage values. This effect was discovered in 1821. Both metal wires produce a voltage proportional to their temperature difference ( it is always measured relatively). Through a series connection ...

Thermopile Area Array Readout |

JPL linear array thermopile detectors are fabricated by bulk micro-machining. Micro-machined thermopiles bump bonded to a ROIC are desirable for area (2-D) focal plane arrays (FPAs) because the architecture provides both high detector fill factor and circuit fill factor in the pixel. The proposed innovation is to develop an area array ROIC compatible with bump bondable micro-machined ...

Thermopile | Working Principle | THE INSTRUMENT GURU

When the sensor is placed at distance not nearly hot object, the output of a single thermocouple will be quite small to detect. For this reason, instrument manufacturers offer a series-connected array of thermocouples called a thermopile to generate a stronger electrical signal (in range of 10 to 100mV). A conceptual diagram of sensor using thermocouples is given as follows-

Thermometrics Thermopile IR Sensor Applications

• A good thermopile detector will have a small NEP. • The thermopile detectors of different sizes will have different NEPs. So we cannot say, in general, what a good NEP should be, unless we specify the size of thermopile detector. Detectivity has been introduced to include device noise and sensitivity simultaneously. It is usually normalized with respect to detector size and noise ...

An Introduction to Thermopile Detectors

Thermopile detectors consist of an array of thermocouple junctions linked in series as differential pairs. These differential pairs form the hot and cold junctions as shown in Figure 1. Alternating n-type and p-type materials called ‘Arms’ connect these junctions and generate a Seebeck effect between them. A voltage is generated in proportion to the temperature gradient between the cold ...
