Pyroelectric coefficient direct measurement technique and application to a nsec response time detector

A direct method for measuring pyroelectric coefficients is described. The method is more straightforward than either the dynamic method or the charge integration technique. Pyroelectric coefficients measured by the direct measurement technique are applied to the design of pyroelectric detectors. A SrxBa1-xNb2O6 detector is described with variable response times from 1 msec to 4 nsec.
