    摘要： According to an aspect of the present inventive concept there is provided a device for polarization dependent imaging, comprising:



    a detector comprising light sensitive elements;
    a plurality of light propagating units, each comprising a polarization splitter having a receiving end for receiving incident light, and comprising a first and a second waveguide.




    The first and second waveguides comprise a first and second portion of the receiving end. The first and second waveguides comprise a first and second distributing end, separate from each other. The polarization splitter is configured to propagate received light to the distributing ends. Each of the portions has an elongated shape such that propagation of light in the waveguides is dependent on the light's linear polarization. The elongated shapes are angled with respect to each other, such that the waveguides are configured to propagate different linear polarization directions.
    Each light propagating unit is arranged such that light at the first and second distributing ends is output towards a first and second light sensitive element, respectively.

    摘要： An imaging polarimeter sensor includes an achromatic beam-splitting polarizer that receives a polychromatic image beam of a scene and simultaneously produces a first polarized polychromatic image beam and a second polarized polychromatic image beam. The second polarized polychromatic image beam is of a different polarization than the first polarized polychromatic image beam and is angularly separated from the first polarized polychromatic image beam. The achromatic beam-splitting polarizer preferably includes a Wollaston prism through which the polychromatic image beam passes, and at least one grating through which the polychromatic image beam passes either before or after it passes through the Wollaston prism. An imaging detector receives the first polarized polychromatic image beam and the second polarized polychromatic image beam and produces an output image signal responsive to the first polarized polychromatic image beam and the second polarized polychromatic image beam.

    摘要： An accurate and robust wavefront-division polarimetric analysis method and device, allows the quasi-instantaneous measurement of the polarization states of a luminous object. The device can be used to produce a plurality of light beams, all polarized according to different polarization states, from a single upstream light beam. The polarized light beams, which do not overlap and which carry information items that are complementary in terms of polarization, are analyzed simultaneously by a plurality of detectors that measure the luminous intensity of each beam. Processing elements digitally process the luminous intensity values obtained in order to determine the polarization state of the upstream light beam. The operations performed by the processing elements prevent luminous intensity variations in the split light beams during the division of the wavefront of the upstream light beam. Therefore, the wavefront-division polarimetric analysis device is robust and its accuracy is not hindered by the experimental conditions.

The pixel matrix is located in substantially non intersecting optical paths of said output beam components and generates a corresponding number of output data pieces indicative of intensity distribution within said output beam components, respectively, data contained in said data pieces being indicative of the polarization profile along the cross section of the input optical beam.
