Abstract

Pyroelectric devices require a change in temperature in order to generate a useful signal. For this reason, Thin Film Ferroelectric (TFFE) sensors require a chopping system to modulate the incident thermal radiation. This chopping or modulation process translates the signal of interest from DC to the chopping frequency, enabling the use of filtering techniques to minimize the effects of 1/f noise.
