…Unlike all other thermal detectors, pyroelectrics measure
the rate of change of the detector temperature, rather
than the temperature value itself. As a result, the response
speed of the pyroelectric is usually limited by its electrical
circuit design and the thermal resistance…

Sensors
For many years thermopiles have been the detector of choice for
high power lasers. These detectors operate on the thermoelectric
principle in which thermal energy is converted into electrical energy.
The typical thermopile has a central,…
