Ferroelectric ceramic thin film infrared detector is an uncooled infrared thermal detector that has great application potential for thermal imaging devices, owing to its very high sensitivity.

The thermal design of the microbolometer FPA is a difficulty and key problem when an uncooled infrared microbolometer detector is designed.

However, since the non-uniformity of the detector can severely constrain its practical application, it has become the focus in the current infrared thermal imaging research.
