A solid-state imaging device comprising an imaging area having unit cells, a vertical driving circuit, signal processing circuits, a horizontal driving circuit, and an output circuit. Signals are continuously applied to an access flow regulator indicating the busyidle state of each memory. Each of a pair of mounts is positioned on the peripheral wall. The lower section includes a secondary lens andor internally reflexive conical element allowing the introduction of radiation, in parallel, into tubes or optical fibre, or irradiation onto radiation converting systems. The signal source may produce sound waves directly or with the assistance of a transducer. The multi-directional aspect of the fiber optic connections permit the connections to be aligned closely with the direction of travel of the fiber optic cables that interface with the device.
