Abstract
The physics of pyroelectric detectors is reviewed, including a discussion
of response and electronic noise and their dependence on device design
and material parameters. Other sources of noise are described, particularly
as generated by environmental effects such as microphony, together
with techniques for their minimization. The range of ferroelectric
materials which have been assessed for use in pyroelectric detectors
is reviewed and their properties compared, particularly from the
aspect of application to different types of device. Finally, an account
is given of the wide range of applications for which pyroelectric
detectors have been used, including a detailed description of both
the pyroelectric vidicon and pyroelectric arrays and their application
to thermal imagers.
