Pyroelectric linear arrays and their application

摘要

For about 15 years, the Solid-State Electronics Lab at the TU Dresden in co-operation with the DIAS Infrared GmbH has been developing pyroelectric linear arrays on the basis of lithium tantalate. These arrays have up to 256 responsive elements and are responsive in the wavelength range of 0.8 … 25 μm. The geometry of the elements can be easily adjusted to the actual application. The available array technology allows the cost-effective production of linear arrays with a high signal-to-noise ratio and an excellent long-term stability. The paper describes the essential properties of the manufactured and newly developed linear arrays and also their applications in contactless temperature measurement, spectrometry and security systems.
