ABSTRACT:
A thermal imaging device having both serial and parallel content is provided by a number of infra-red radiation detector strips supported side by side on an insulating substrate, each strip having a number of read-out regions. To allow connection from the side of the device to the innermost detector strips, conductors err end across outer strips. These conductors may extend over the strips and over insulating material therebetween. Alternatively the conductors may be in the form of conductive tracks embodied in a substrate of semiconductor material. The strips may be indented at the read-out regions to provide, with very close spacing, sufficient room for contact between the read-out regions and the conductive tracks. Preformed aluminium contact pads may be used between bridging links to the read-out regions and the conductive tracks the contact pads and preformed tracks being centered during preformation to ensure a good ohmic contact.
