    Abstract: Disclosed is an optical fibre birefringence compensation mirror which as well as being easy to align and assemble, compensates for the birefringence generated by a sensor optical fibre, particularly in current sensors, increases the vibration resistance of a current sensor, and enables large current detection by a current sensor. Also disclosed is a current sensor wherein vibration resistance has been increased due to the optical connection of the optical fibre birefringence compensation mirror. The optical fibre birefringence compensation mirror comprises: an optical fibre, a birefringence element, a lens, a magnet, a Faraday rotator, and a mirror. From the light incidence/emission end surface of the optical fibre, the birefringence element, Faraday rotator, and mirror are arranged in said order, and the optical fibre is a single mode type optical fibre. Light comes in from the optical fibre, and is separated into two linearly polarised lights by the birefringence element. The polarisation planes of the two linearly polarised lights are rotated by 45 degrees by the Faraday rotator, and the two linearly polarised lights are point-symmetrically reflected at one point by the mirror, then once again rotated by 45 degrees by the Faraday rotator, then re-combined to be one light by the birefringence element and made to enter the optical fibre.

    Abstract: The birefringent filter unit includes a planar birefringent plate arranged such that the light enters the birefringent plate at an approximate Brewster's angle, a first reflecting member arranged substantially parallel to the birefringent plate to allow the light having passed through the birefringent plate to enter the birefringent plate at the approximate Brewster's angle, and a second reflecting member arranged opposite to the first reflecting member and substantially parallel to the birefringent plate, which allows the light having passed through the birefringent plate after being reflected by the first regulating member to enter the birefringent plate at the approximate Brewster's angle.

    Abstract: An imaging apparatus and method are provided for improving discrimination between parts of a scene enabling enhancement of an object in the scene. A camera unit is arranged to capture first and second images from the scene in first and second distinct and spectrally spaced apart wavebands. An image processing unit processes the images so captured and processes polarimetric information in the images to enable better discrimination between parts of the scene. An image of the scene, including a graphical display of the polarimetric information, may be displayed on a visual display unit thus enhancing an object in the scene for viewing by a user. Correlation parameters indicating, possibly on a pixel-by-pixel basis, the correlation between the actual image intensity at each angle of polarization and a modelled expected image intensity may be used to enhance the visibility of an object.

    Abstract: A polarization image capturing section 103 obtains a first polarization image containing polarization information. A polarization information obtaining section 104 obtains first polarization information from the first polarization image. An illumination control section 102 changes an illumination section 101 and again obtains a second polarization image by means of the polarization image capturing section 103. The polarization information obtaining section 104 obtains second polarization information from the second polarization image. A light source dependency estimation section 105 obtains light source dependency from the first and second polarization information obtained from the first and second polarization images. An area dividing section 106 performs an area division by using the polarization information and light source dependency information.
