electrical engineering. SUBSTANCE: fiber-optical device to register shape of pulses of superheavy currents includes fiber-optical measuring unit, recorder and analog differentiating-integrating unit whose two inputs are connected to outputs of fiber-optical measuring unit correspondingly and whose output is linked to input of recorder that is capable of memorizing shape of signal in digital or analog form. According to one version of implementation of device analog differentiating- integrating unit incorporates differentiator, two multipliers, integrator and adder whose output is output of analog differentiating-integrating unit. In agreement with another version analog differentiating-integrating unit has two differentiators, two multipliers and adder whose output is connected via integrator to output of analog differentiating- integrating unit. EFFECT: diminished frequency band of signals coming to input of recorder, simplified design of device. 2 cl, 4 dwg
