Investigation of Pyroelectric and Pyromagnetic Detection

Abstract

The capacitive bolometer effect must be described in terms of the d-c capacitance c(d) = Q/V. The effect can also be interpreted as an induced pyroelectric effect. The noise in d-c biased capacitive bolometers must be interpreted as polarization noise, enhanced by the d-c field. The molecular field theory of ferroelectricity has been applied to the evaluation of p/epsilon and p/epsilon sup 1/2 shows the right order of magnitude.
