Pyroelectric Sensitivity of Triglycine Sulfate Detectors

摘要

Expressions are derived for the theoretical pyroelectric current sensitivity of triglycine sulfate in response to chopped or modulated electromagnetic radiation. Sinusoidal chopping, amplitude modulation, square wave modulation, pulses, and step functions of the radiation are considered. These expressions are compared with the experimental results achieved with various pyroelectric detectors, and it is found that the sensitivity achieved varies from a fraction of a percent to approximately 100 percent of the theoretical values.
