Noise in Pyroelectric IR Detectors App Note 13-02 The noise mechanisms discussed above are for the case where the impedance conversion is made with a JFET connected as a source follower. We now discuss the case where the impedance conversion is made with a current to voltage converter or transimpedance amplifier. Today there are quite a good number of opamps which have very low input …

Hyperspectral IR images contain a contiguous spectrum in the bandwidth of IR in a spatial scanline in the scene and allow the technique of combining spectroscopy and imaging, which makes it very well suited for human victim detection. Pyroelectric sensors are another type of heat-based human detector. These sensors are designed specifically for human detection. The sensor is made of a ...
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.
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 flux and so systems based upon ...
Figure 1 shows the principle set-up of a pyroelectric infrared detector. Components are theresponsive element and the preamplifier whose essential elements are integrated in thedetector. The sensitive element consists of a pyroelectric chip which is thin and covered withelectrodes. In some cases an absorption layer is applied to the front of the responsive elementto improve its absorption behavior.
The pyroelectric infrared sensors from InfraTec, also called pyroelectric detectors, can detect the electromagnetic radiation (UV, VIS, IR, THz) that hits them and measure their intensity. When the radiation hits, the pyroelectric crystal heats up and positive electrical charges occur.

Fast response of ezPyro™ SMD pyroelectric sensors enables energy saving in NDIR gas measurement applications, as the sensor responds optimally to IR source pulses as short as 25 ms. This is >10x shorter than a typical infrared bulb with thermopile gas measurement configuration.
Pyroelectric IR detectors are also indispensable in medicine. Thus, the function of the lungs can be analysed by measuring CO2. Or diseases can be identified in the breath by other measurements. The correct mixture of anaesthetic gases is also determined with detectors from InfraTec. And not least of all, breath alcohol measurements should ensure that only sober drivers are allowed to drive in ...
Due to the physical principle of operation, pyroelectric infrared detectors can detect radiation in a very broad wavelength spectrum from about 100 nm (UV) to more than 1 mm (terahertz waves) without series of PYROSENS single- and multi-channel detectors is optimized for the spectral range between μm and 30 μm. Depending on the type, the PYROSENS detectors are equipped with ...

Pyroelectricity (from the two Greek words pyr meaning fire, and electricity) is a property of certain crystals which are naturally electrically polarized and as a result contain large electric fields. Pyroelectricity can be described as the ability of certain materials to generate a temporary voltage when they are heated or cooled.
