13-355nm and μm - Pyroelectric Array Camera

3 pyroelectric crystal mounted with indium bumps to a solid-state readout multiplexer. This sensor, developed for the Pyrocam I, has proven to be the most rugged, stable, and precise IR detector array available. Light impinging on the pyroelectric crystal is absorbed and converted to heat, which creates charge on the surface. The multiplexer then

Pyroelectric linear array sensor for object recognition

Sensor Specifications. A schematic of the PLA sensor is shown in Fig. research indicated that 17 samples over a human, of height 2 m, provided sufficient information for accurate target discrimination. 9 The design process started with the choice of a Dias 128 element linear array of pyroelectric detectors. The size of each detector is 90 μ m × 100 μ m with a pitch of 100 μm.

IRISYS REDEYE-6A Pyroelectric Array Sensor

is an array sensor using pyroelectric ceramic. The manufacturing process is simpler than it is for a micro-bolometer. The ceramic plate is attached on top of the readout integrated circuit and sealed with the IR window. The definition of the REDEYE-6A is rather low: 31x31 pixels. It is optimized for low-cost application which do not need a great definition and high refresh rate. The same ...

Pyroelectric IR sensor arrays for fall detection in the ...

Uncooled pyroelectric sensor arrays have been studied over many years for their uses in thermal imaging applications. These arrays will only detect changes in IR ux and so systems based upon them are very good at detecting movements of people in the scene without sensing the background, if they are used in staring mode. Relatively-low element count arrays (16x16) can be used for a variety of ...
