A pyroelectric thermal imaging camera tube

This paper proposes the use of a thin slice of a pyroelectric single crystal as the target of an electron beam scanned camera tube. This target would be sensitive to thermal images generated by black body radiation. It is shown that 10

of a TGS target at a frame rate not lower than 10 Hz and a thermal resolution of 1°C in the scene should be obtainable. A pyroelectric thermal imaging camera tube based on these principles has been built and its operation will be described elsewhere [1].
