A detector for determining the location of a pulsed laser spot reflected from a scene, which comprises a CCD sensor for imaging the scene comprising an array of pixels arranged in rows (R, R, R) and columns (C, C, C), a serial read-out register arrangement (not shown), and charge transfer electrodes (&#xd8;H, &#xd8;V, &#xd8;) capable of transferring signal charge in at least two adjacent pixels to read-out register arrangement locations representative of the row location of at least one of the adjacent pixels and the column location of at least one other of the adjacent pixels. The charge transfer electrodes are two phase, but three or more phase arrangements are also possible.

Detector for determining the location of a laser spot

A sensor device of the type for sensing incident radiation by charge generation, has a substrate within which charge may be generated by incident radiation. A plurality of electrodes are arranged to cover an image area of the substrate and are selectively connectable to supplied DC voltages such that an electric field is created across the image area to sweep charge across multiple electrodes from the image area to an output. The voltage applied to one of the electrodes may be a voltage of a level so as to present a barrier to charge within the image area. The sensor thus has a variable sample area defined by the barrier voltage level.

Variable aperture sensor

A multiplication register for use in solid state imaging apparatus, such as a CCD, is described. The multiplication register has a gain elementcomprising a plurality of register electrodes, and, for transferring charge along a change transfer channel, and for amplifying the charge. Channel edge defining electrodesandare disposed either side of the channel, in place of channel stops, removing the effects of spurious charges generated in the channel in the regions of amplification. The provision of the channel edge defining electrodesandallows the resulting structure of the channel electrodes to be made simpler, and means that a structure can be provided for clocking and amplifying charge in either direction along the channel.
