How Is Pyroelectric Current Measured

The pyroelectric current measurements use either bulk heating for low frequency periodic (LFP) measurements, microfabricated resistive heaters for 2ω measurements, or a chopped laser beam for laser intensity modulation (LIM) measurements.

How does a pyroelectric detector work?

Pyroelectric detectors are thermal detectors: Temperature fluctuations produce a charge change on the surface of pyroelectric crystals, which produces a corresponding electrical signal. This temperature gradient can be created by the absorption of light.

What is meant by Pyroelectricity?

Definition of pyroelectricity : a state of electrical polarization produced (as in a crystal) by a change of temperature.
