Abstract: An electrical current measuring device, for measuring the current in an electrical conductor (11), includes first and second measurement channels. Each of these channels includes a sensor (12) adapted to be located adjacent the conductor (11) and coupled via optical fibers (14,16) to source circuitry (18) and detector circuitry (20). The sensor (12) incorporates a material (22) which exhibits the Faraday magneto-optic effect and the source circuitry (18) is arranged to deliver an unpolarized light signal which is subsequently polarized by a first polarizer (23) to enable a linearly polarized light signal to be incident to the material (22). The quantum of rotation in the plane of polarization imposed on the signal emerging from the material (22) is monitored via a second polarizer (24) by the detector circuitry (20) as a measure of the electrical current flowing in the conductor (11).

Abstract: An optical signal processor (1) used with a method of processing optical data has at least one optical coupling unit (12). Each coupling unit (12) has two optical couplers (12A, 12B) which are connected so that principal channels (14) are connected in series with a time delay of a predetermined value between adjacent couplers (12A, 12B). The optical coupling units (12) are formed into stages. The number of optical coupling units (12) or stages determines further coding of each bit of the input optical signal or code sequence. Stages can be coupled together to process a sequence of optical pulses corresponding in number to the number of optical coupling stages in the system. The outputs of each stage are coupled via optical switches (18) to an optical summing device (24) to simultaneously process the coded data and determine whether the processing has resulted in matching or mismatching of data.
