Pyroelectric linear array IR detectors with CCD ...

Responsive pyroelectric linear arrays are described. After a short representation of the principal detector function, the pyroelectric materials L-alanine doped triglycine sulfate (DTGS:L-A) and lithium niobate (LiNbO3) are characterized, and the system parts pyroelectric chip, CCD-multiplexer, and hybrid arrangement are described in detail. Finally, the measured properties responsivity, noise ...

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.

A Charge Coupled (CCD) Pyroelectric Array - NASA/ADS

The CCD incorporates sixteen rows of sixteen element analogue multiplexers. Direct charge injection into the CCD channel is achieved via an array of pads on the top of the CCD which are bonded directly to the pyroelectric, currently with an array of screen printed epoxy resin dots. A solder bonding technique is preferred, but is still under ...

Pyroelectric Thin Films Integrated with CCD: Ingenta Connect

A theoretical model of uncooled focal plane array (UFPA) based on pyroelectric thin film integrated with CCD is proposed. The model of UFPA was designed around the heat balance equations and equivalent circuit. A modified technology of integrated structures of multi-element pyroelectric detectors and special-purpose CCD is proposed. There are designer and manufactured a completely monolithic ...

Interface Design For The Pyroelectric/CCD Hybrid

The pyroelectric vidicon camera tube has given rise to a range of inexpensive thermal imagers which operate at ambient temperatures, without a requirement for cooling, and are suitable for all but the most demanding roles. The pyroelectric retina of the camera tube is equivalent to a large two dimensional array of detector elements which is addressed and read out by the electron beam. Because ...

PIR Motion Sensor - Adafruit Industries

2020-01-25· Infrared", "Pyroelectric", or "IR motion" sensors. PIRs are basically made of a pyroelectric sensor (https:///aKh) (which you can see below as the round metal can with a rectangular crystal in the center), which can detect levels of infrared radiation. Everything emits some low level radiation, and the hotter something is, the more radiation is emitted. The sensor in a motion detector ...

Pyroelectric infrared-CCD image sensor using LiTaO3 ...

1989-03-01· A room-temperature-operated CCD infrared-image sensor having 64 × 32 elements has been developed by combining a pyroelectric LiTaO 3 single crystal and a Si CCD. A LiTaO 3 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.

Pyroelectric/CCD Hybrid Focal Plane - NASA/ADS

A pyroelectric detector/Si CCD hybrid focal plane operates at room temperature, and may prove useful in applications where the sensor performance requirement is moderate but low cost is essential. Flip-chip, bump mounted LiTa0 3 /CCD modules are under development at Honeywell (see Figure 1). A one dimensional thermal model of the pyroelectric detector response has been developed.
