Abstract

1395741 Image pick-up tubes THOMSONCSF 12 May 1972 [14 May 1971] 22549/72 Heading H1D A pyroelectric target for thermal carrier tubes comprises a substrate 4 of low thermal conductivity, a transparent conducting layer 3, e.g. Au, and a mosaic of elements 1 of pyroelectric material. To increase radiation absorption an opaque layer 2 is added. Square elements of monocrystalline triglycine sulphate are attached to the layer 2 by an adhesive film 5. Read-out is by a scanning electron beam. The target is formed by depositing a mosaic of Au elements on a continuous layer of pyroelectric material and etching the material between the Au elements.
