چکیده

Pyroelectric and dielectric properties of modified PZT and PZ have been studied for their use in infrared detectors. Various material figure-of-merits for their use in infrared detector are calculated including when the pyroelectric element is placed on heat-sink condition. The results are compared with exiting candidate materials.

Selective Pyroelectric Detection of Millimetre Waves Using Ultra-Thin Metasurface Absorbers.

Sensing infrared radiation is done inexpensively with pyroelectric detectors that generate a temporary voltage when they are heated by the incident infrared radiation. Unfortunately the performance of these detectors deteriorates for longer wavelengths, leaving the detection of, for instance, millimetre-wave radiation to expensive approaches. We propose here a simple and effective method to enh...

The evaluation of a pyroelectric detector with a carbon multi-walled nanotube coating in the infrared

The performance of a pyroelectric detector with a carbon multi-walled nanotube coating was evaluated in the 0.9 μm to 14 μm wavelength range. The relative spectral responsivity of this detector was shown to be flat over most of the wavelength range examined and the spectral flatness was shown to be comparable to the best infrared black coatings currently available. The performance of the detect...

Identification of glass and ceramics by X-ray fluorescence analysis with a pyroelectric X-ray generator.

Applications of X-ray fluorescence (XRF) analysis with a pyroelectric X-ray generator are presented. Glass and ceramics were analyzed with this novel X-ray generator to examine its capability for analyzing nonmetallic inorganic material. Although the power of X-ray output was a few orders of magnitude lower than conventional X-ray tubes, many elements such as Si, K, Ca, Ti, Cr, Fe, Zn, Sr, Ba, ...
