Paper Abstract

Distributed parameter model is used for computation of the performances of single pixel of PZT ferroelectric thin film infrared uncooled focal plane array (IR-UFPA) with two kinds of thermal isolation structures. The detector performances are found to be related closely to the thermal isolation structure. The preferred thickness of pyroelectric thin film is in the region of 0.3 - 2 micrometers for pixel dimensions 50 X 50 and 100 X 100 micrometers 2. And the preamplifier current noise is the dominant noise when it more than 10-16 A(DOT)Hz-1/2 in PZT-UFPA device.
