Pyroelectric Detectors - LASER COMPONENTS

A pyroelectric IR detector is a thermal detector in that it responds to the change in heat (IR) absorbed on its surface. Thermal detectors are polychromatic with a very wide spectral bandwidth. The nature of the pyroelectric effect is that in a highly-ordered crystal (or ceramic), a temperature change in the element causes its atoms to move ...

Thin film pyroelectric array as a detector for an infrared ...

We demonstrate the implementation of a thin film pyroelectric array as a detector in an infrared gas spectrometer. The 1 x 50 element array is integrated onto a silicon chip with a sol-gel deposited zirconium modified lead titanate film (PZT) as the pyroelectrically active layer and a submicron membrane for thermal insulation. The spectrometer fitted with this detector covers a spectral range ...

Pyroelectric thin-film sensor array - ScienceDirect

May 01, 1997· Pyroelectric thin-film point detectors and 1 × 12 arrays have been fabricated and characterized. They consist of sol-gel-deposited PZT thin-film elements on micromachined Si 3 N 4 /SiO 2 membranes. The measured current and voltage response as a function of modulation frequency of a 1 × 12 array element is compared with finite-element calculations.
