Abstract: A system and method for detection and measurement of circular birefringences in materials that exhibit the Faraday effect. The method and apparatus permit detection of optical activities via the difference in the directions of propagation the left- and the right-circularly polarized light (components). A beam of light is directed at an interface formed by the optically active medium and another medium such that a difference in the angles of refraction and/or reflection and/or diffraction between the left- and the right-circularly polarized components of the light beam can be detected. The difference in the propagation directions between the two circularly polarized light components is measured on a position sensitive detector and/or is detected as an intensity difference.

Abstract: A system and method for detection and measurement of circular birefringences in materials, such as optically active (chiral) liquids and materials that exhibit the Faraday effect. The method and apparatus permit the detection of optical activities via the difference in the directions of propagation the left- and the right-circularly polarized light (components). A beam of light is directed at an interface formed by the optically active medium and another medium such that a difference in the angles of refraction and/or reflection and/or diffraction between the left- and the right-circularly polarized components of the light beam can be detected. The difference in the propagation directions between the two circularly polarized light components is measured on a position sensitive detector and/or is detected as an intensity difference. The circular birefringence in isotropic liquids is a measure of their optical purity (enantiomeric excess) and hence the invention presents a method and apparatus to measure chirality. The invention is thus related to optical rotation (polarimetric) measurements, but has the advantage that it does not depend on path-length traversed through the sample.

Abstract: 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.

Abstract: Each of a detection sample object and a non-detection sample object is illuminated with S-polarization light, for instance. S-polarization light and P-polarization light reflected from each sample object are detected by different photodetecting elements. Glossiness values and light quantities of the detection and non-detection sample objects are judged based on detection outputs of the photodetecting elements, and a glossiness difference and a light quantity difference are calculated. An evaluation function having at least one of the glossiness and the light quantity as a variable is determined by using the glossiness difference and the light quantity difference. Thresholds for object discrimination are calculated based on evaluation function values of the detection and non-detection sample objects.
