    Abstract: An ellipsometer for determining thickness and ellipsometric parameters (Ψ and Δ) of a thin film material. The apparatus includes a light source emitting light, a transmitting optical system that has a polarizer, modulator and an optical compensator for conveying polarized modulated light for incidence on a film, and a receiving optical system that has an analyzer and conveys the reflected light to a photodetector device. The apparatus is used for full range measurement of ellipsometric parameters by applying two-phase detection method. It also determines thickness of thin films with a high degree of accuracy.

    Abstract: The present invention relates to a multi-energy system that generates and/or forms images of targets/structures by applying Mueller matrix imaging principles and/or Stokes polarimetric parameter imaging principles to data obtained by the multi-energy system. In one embodiment, the present invention utilizes at least one energy or light source to generate two or more Mueller matrix and/or Stokes polarization parameters images of a target/structure, and evaluates the Mueller matrix/Stokes polarization parameters multi-spectral difference(s) between the two or more images of the target/structure. As a result, high contrast, high specificity images can be obtained. Additional information can be obtained by and/or from the present invention through the application of image, Mueller matrix decomposition, and/or image reconstruction techniques that operate directly on the Mueller matrix and/or Stokes polarization parameters.

    Abstract: A variably-polarizing optical probe assembly. The assembly includes an optical probe having one or more optical light delivery channels that emit incident light from the sample end of the probe toward a sample being investigated, and one or more optical light-receiving channels that receive incident light from the sample. A variably-polarizing substrate assembly is coupled to the sample end of the probe. The substrate assembly includes an optically transmitting substrate and one or more discrete polarizer areas on a face of the substrate, each such polarizer area defining a polarization orientation, with the polarizer areas together defining one or more different polarization orientations. The substrate assembly is arranged relative to the probe such that one polarizer area covers at least one light delivery channel and one polarizer area covers at least one light-receiving channel.
