摘要： A method for detecting and measuring physical perturbations sensed by a multi-mode waveguide, through which a number of modes of a coherent electromagnetic wave propagates through and exit from. The method comprises irradiating the exiting electromagnetic wave on one or more two-dimensional sensing arrays comprising a plurality of sensing elements that are sensitive to the irradiated electromagnetic wave; determining, simultaneously, in a parallel manner, absolute values of sensed changes across different zones of the two-dimensional sensing arrays, each zone comprising one or more sensing elements; and summing the absolute values of different groups of different zones to obtain a representation of the perturbations.

摘要： A method for recovering an initial linear state of polarization, of an optical beam after the beam has passed through an optical fiber and whose polarization state was disrupted, attaining power which is directly proportional to the power of the beam before it has passed through the optical fiber. The method comprises: splitting the beam into two beams, a first beam with a first polarization state and a second beam with a second polarization state, the second polarization state being orthogonal to the first polarization state; changing the polarization state of the first beam; and combining the first and second beams in half of their intensities into at least one linearly polarized beam. This way a linearly polarized output beam with power that is directly proportional to the power of the beam prior to its passing through the optical fiber is achieved.

摘要： A method for recovering an initial linear state of polarization, of an optical beam after the beam has passed through an optical fiber (11) and whose polarization state was disrupted, attaining power which is directly proportional to the power of the beam before it has passed through the optical fiber. The method comprises: splitting the beam into two beams, a first beam (21) with a first polarization state and a second beam (22) with a second polarization state, the second polarization state being orthogonal to the first polarization state; changing the polarization state of the first beam; and combining the first and second beams in half of their intensities into at least one linearly polarized beam (25). This way a linearly polarized output beam with power that is directly proportional to the power of the beam prior to it passing through the optical fiber.
