Paper Abstract
In many fields of IR technology it is necessary to take a parallel measurement of IR radiation within various defined spectral ranges. And in many cases there is also the demand for an identical measuring dot (moved objects), a high responsivity, a high signal-to-noise ratio, and a minimum cross talk. The paper describes the hybrid arrangement and essential properties of the developed pyroelectric multispectral detectors disposing of up to four channels. The detectors are discrete and handy building bricks fit into a T0 8 case which has an aperture of 2 mm in diameter and an internal spatial and spectral dispersion of the total radiation. It also presents results of these detectors applied especially in a multispectral pyrometer and the possibility of using them in gas analyzers. By using them in a multispectral pyrometer and applying special evaluation algorithms it was possible to reduce the influence of emission rate on the measuring accuracy decisively.
