Abstract: A method using Long Wave Infrared Imaging Polarimetry for improved mapping and perception of a roadway or path and for perceiving or detecting obstacles comprises recording raw image data using a polarimeter to obtain polarized images of the roadway or area. The images are then corrected for non-uniformity, optical distortion, and registration. IR and polarization data products are computed, and the resultant data products are converted to a multi-dimensional data set for exploitation. Contrast enhancement algorithms are applied to the multi-dimensional imagery to form enhanced object images. The enhanced object images may then be displayed to a user, and/or an annunciator may announce the presence of an object. Further, the vehicle may take evasive action based upon the presence of an object in the roadway.

Abstract: Disclosed are a light polarization state detection apparatus, a detection method and a light polarization state modulation method. The light polarization state detection apparatus comprises a lens with a variable birefringence feature as an optical phase modulator, a polarizer as a SOP analyzer, a plurality of common lenses and a CCD as imaging devices, and a data processing and displaying unit. The SOP detection apparatus uses special birefringence distribution of birefringence optical elements such as a GRIN lens to obtain the Stokes parameters of light to be measured by CCD in a single frame imaging, and can rapidly accurately measure the SOP. The SOP detection apparatus is simple in structure, lower in cost without containing any motion parts and electrical modulation devices, and is a fully static full Stokes parameters SOP detection apparatus. The light polarization state modulation apparatus comprises a GRIN lens with a variable birefringence feature. The modulation method is continuous in each position of a modulation aperture, rich in modulation variety and low in cost.

Abstract: According to the invention, the fibre direction of a carbon-fibre material of an object which is to be tested is detected using the polarisation direction of light reflected by the object which is to be tested. If unpolarised light, for example, is incident on carbon-fibre, the light reflected by the fibres is polarised in the fibre direction.
