FIELD: information-measuring technique. ^ SUBSTANCE: fiver-optic device can be used in digital registration systems for registering single-time pulse image of density of flow of ionizing radiation when making tests on nuclear physics. Fiber-optic device for visualization of pulse ionizing radiation flow density distribution has N similar fiber-optic screens. Any screen is made in form of rectangular frame; cuts K of optical fiber with equal lengths are pulled against frame in parallel to each other. Fiber-optic deice also has NxK fiber-optic delay lines, N similar fiber-optic data transmission lines, multiple channel fiber-optic registrar provided with screen, N similar optical adders, each of which adders has K inputs and single output. Input of any fiber-optic delay line is connected with corresponding cutoff optical fiber of corresponding fiber-optic screen. Output of any fiber-optic delay line is connected with corresponding input of optical adder. Outputs of all optical adders are connected to corresponding inputs of multiple channel electro-optic registrars through fiber-optic data transmission lines. ^ EFFECT: reduced distortion of image caused by radiation damage of fiber optic cuts. ^ 2 dwg
