Pyroelectric infrared detectors using sol-gel deposited lead zirconate titanate (PZT) thin films were fabricated. It was found that specific detectivity D\* of the detector is a strong function of the modulation frequency of the incident radiation. Noise plays an important role at low frequencies (
