Thermal imaging using pyroelectric detectors

The pyroelectric detector is a new radiation detector that employs the temperature sensitivity of electrostatic polarization as the sensing principle. Electrically, the detector behaves as a capacitance on which a charge appears when thermally irradiated. This detector has a number of features that make its use attractive for thermal imaging. It does not require cooling, and no biasing voltage ...

Pyroelectric infrared image sensors using Si CCD and FET ...

1994-02-01· Two types of infrared image sensors have been developed by combining a pyroelectric plate with an Si FET array and an Si CCD, respectively. One is an image sensor in which a pyroelectric LiTaO 3 plate is bonded to an Si FET array of 64 × 64 elements by indium bumps. The other is an LiTaO 3 or PZT plate connected to an Si CCD of 64 × 32 elements by a dielectric connector.

Thermal Imaging Systems Utilizing Pyroelectric Detector ...

Pyroelectric detectors have the advantage of being inherently accoupled to the target scene and they are therefore ideally suited for use in high-background and/or long-wavelength thermal imaging systems. This paper presents the results of a study to determine the feasibility and to predict the performance of focal planes employing very thin pyroelectric detector arrays together with solid ...
