    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 method for imaging a sample, the method includes, during a single acquisition event, receiving a first polarization-encoded EM field for a first point and a second polarization-encoded EM field for a second point. The method further includes redirecting the first polarization-encoded EM field along a first pre-determined direction to a first location on a dispersing re-imager and the second polarization-encoded EM field along a second pre-determined direction to a second location on the dispersing re-imager. The method further includes spectrally dispersing the first polarization-encoded EM field to obtain a first spectrum, re-imaging the first spectrum onto a first location on a detector, spectrally dispersing the second polarization-encoded EM field to obtain a second spectrum, re-imaging the second spectrum onto a second location on the detector, and detecting the first re-imaged spectrum and the second re-imaged spectrum.

    Abstract: Embodiments of a system and method for collecting hyperspectral and polarimetric data that are spatially and temporally coincident include a dispersive element configured to receive incident electromagnetic radiation. The dispersive element is configured to disperse a non-zero order of the electromagnetic radiation into its constituent spectra, which is directed to a first focal plane array, and may be read out as hyperspectral data. The dispersive element is also configured to reflect a zero order of the electromagnetic radiation, which is directed through a polarity discriminating element to a second focal plane array, which may be read out as polarimetric data. By synchronously reading out the first and second focal plane arrays, the hyperspectral and polarimetric data may be both spatially and temporally coincident.

    Abstract: An adjustment method for adjusting an illumination condition in illuminating an original plate (30) using an illumination optical system (20) and projecting an image of a pattern formed on the original plate onto a substrate (50) through a projection optical system (40) includes measuring a polarization state of light that has passed through the illumination optical system, the original plate, and the projection optical system in a state where the original plate is located on an object plane of the projection optical system, and adjusting the polarization state based on the measured polarization state.
