Abstract: An electro-optical imaging system uses a charge-coupled bucket-brigade photo-sensitive image convertor where the necessity for light shielded shift registers and other measures for preventing the acquisition of additional incident-light induced charge by light-representative electrical charge packets as they pass to the output port of the convertor is removed by the use of a liquid crystal light transmission cell which can be made transparent for the acquisition of charge by the convertor and opaque for the shifting of the charges to the output port. The convertor can thus be made simpler and of smaller area to give a lower cost and higher production yield. The convertor is given an apparently increased spatial resolution by providing that the cell allows sub-areas of the total image to be transmitted one-by-one to the convertor by the sequential operation of four sub-cells of the main cell such that each sub-cell becomes transparent and has its through-passing image converted in turn.
