    • A charge-coupled device for detecting spatial variation in the intensity of electromagnetic radiation comprises a body of semiconductor material that responds to electromagnetic radiation in a given spectral region by generating charge carriers. The body of semiconductor material has first and second sense volumes that are isolated from each other with respect to diffusion of charge carriers. A sense electrode structure overlies the sense volumes. First and second transfer regions are in communication with the first and second sense volumes respectively, and a transfer electrode structure overlies the transfer regions. A readout region has first and second zones in communication with the first and second transfer regions respectively and is connected to an output node. Charge can be accumulated in the sense volumes over an integration period and the resulting charge samples can be shifted separately through the transfer regions and applied to the output node.

    • A device for detecting spatial variation in the intensity of electromagnetic radiation in a given spectral region comprises a body of semiconductor material that responds to electromagnetic radiation in the given spectral region by generating charge carriers. The body of semiconductor material has first and second charge collection regions separated by a barrier region that forms a potential barrier to the charge carriers in the charge collection regions. The device also comprises an electrode structure for establishing a predetermined potential in the charge collection regions, whereby charge carriers can be accumulated in the charge collection regions, and first and second output devices connected to the first and second charge collection regions respectively for extracting charge therefrom.
