摘要：

The absorption of radiation with pyroelectric detectors and the thermal properties of these devices are discussed using a simple physical picture - the physics of waves. Considered are the reflection, transmission and interference of electromagnetic and of thermal waves within the pyroelectric sensor arrangement. In particular, thin metal films, quarter wavelength structures, and anti-reflection coatings on metal films as absorber structures are discussed. The effect of the substrate on the pyroelectric response is treated and new figures of merit are introduced for the comparison of sensor materials which are mounted on a heat sink.
