Abstract: A system and method for detection of a target object/material includes identifying a polarimetric signal for a plurality of aspect angles. One/two-dimensional Mueller matrix image or one/two-dimensional Stokes vector image can be processed using power spectral analysis, wavelet and fractal analysis for further image, having increased discrimination with reduced false-ratio. In addition, each of the angular polarization states due to their association with a particular aspect angle are then cross-correlated to generate a two-dimensional image that relates the level of correlation with the aspect angle. Finally, the output information, including statistical parameters are fed to the input of a neural-fuzzy network for further optimization and image enhancement.

Abstract: Embodiments described herein describe the construction of frequency domain estimates of generalized power density and the filters that can be constructed from those estimates. Using the concept of the Stokes vector representation of the spectral matrix in an M-dimensional vector space, a generalization of the process in which the spectral matrix may be represented by a set of trace-orthogonal matrices that are based upon a particular signal state can be produced. One aspect of the process is as follows: given a particular signal, represented as by a state vector in the space, a complete, orthonormal set of vectors can be produced that includes the signal of interest. Then, a generalized set of matrices is constructed, based upon the developed vectors, that are trace-orthogonal and which serve as a basis set for the expansion of the spectral matrix. The coefficients of this expansion form a generalized Stokes vector that represents the power in the spectral matrix associated with the various state vectors. Filters that serve to extract or suppress information about a particular state may then be constructed using the components of the generalized Stokes vectors. The effectiveness of an embodiment this filter is demonstrated using acoustic data from a microphone array.

Abstract: The embodiments relate to a method of calculating an image for simulating by calculation an image imaged by a projection optical system. In this method, a Stokes vector showing a characteristic of an illumination light is acquired first. Next, this Stokes vector is divided into a polarized light component vector and a non-polarized light component vector. The polarized light component vector is divided into a first coherent component vector and a first non-coherent component vector. The non-polarized light component vector is divided into a second coherent component vector and a second non-coherent component vector. Then, imaging calculation is performed at least for the first coherent component vector and the second coherent component vector, respectively.

Abstract: A polarimeter and method of polarizing incoming light includes an optical assembly, a first adjustable circular retarder that rotates the polarization content of incoming light, a polarization beam splitter that receives light from the adjustable circular retarder and polarizing the light into a first portion of light having a first polarization and a second portion of light having a second polarization. The first portion of light is directed to a focal plane and the second portion of light is directed to the optical assembly. The optical assembly is switchable between a polarizing mode of operation in which the first portion of light is viewable at the focal plane in absence of the second portion of light and an imaging mode of operation in which the first portion of light and the second portion of light are viewable at the focal plane.
