P12 - Comparison of Pyroelectric and Thermopile Detectors

N. Neumann & V. Banta
Thermal infrared detectors are distinguished by the advantages of a wide wavelength response, no requirement for cooling, high-temperature stability, high signal-to-noise ratio and low cost. Consequently, they are widely used in consumer products and in instrumentation. In the literature one can find many publications with regard to details either of pyroelectric detectors or thermopiles but a comparison of both thermal detectors could seldom be found. The main principles and the basic design of both the...
