Pyroelectric infrared-CCD image sensor using LiTaO3 ...

Abstract A room-temperature-operated CCD infrared-image sensor having 64 × 32 elements has been developed by combining a pyroelectric LiTaO3 single crystal and a Si CCD. A LiTaO3 plate is attached to the Si CCD with liquid glycerin, which has a large dielectric constant, low thermal conductivity and high insulation, and controls the MOS gate for charge injection.

A pyroelectric thermal imaging camera tube - [PDF Document]

· A Pyroelectric Thermal Imaging Camera Tube MICHAEL F. TOMPSETT . Abstract-This paper proposes the use of a thin slice of a pyro- electric single crystal as the target of an electron beam scanned camera tube. This target would be sensitive to thermal images gen- erated by black body radiation. It is shown that lo4 resolvable pic- ture points per cmz of a TGS target at a frame rate not …

Pyroelectric Material - an overview | ScienceDirect Topics

In addition to their application in thermal imaging, pyroelectric materials can also be used for thermal energy harvesting [73, 74, 134–136]. As the pyroelectric current flowing through a material is proportional to the rate of change of temperature with time rather than its absolute value (Eq. ), pyroelectric energy harvesting is more suitable for the sources having a continuous ...

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 ...

Pyroelectricity: From Ancient Curiosity to Modern Imaging ...

· Pyroelectric thermal detectors have five main advantages: ... The earliest version of a device for two-dimensional pyroelectric imaging was developed in the late 1970s. It was a modified television vidicon tube with a TGS target, electron beam readout, a germanium lens, and a light chopper. The problem was that lateral thermal diffusion in the target in the time between electron-beam sweeps ...

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

· 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.
