Abstract. An objective analysis is carried out of the matricial models representing the polarimetric properties of light and material media leading to the identification and definition of their corresponding physical quantities, using the concept of the coherency matrix. For light, cases of homogeneous and inhomogeneous wavefront are analyzed, and a model for 3D polarimetric purity is constructed. For linear passive material media, a general model is developed on the basis that any physically realizable linear transformation of Stokes vectors is equivalent to an ensemble average of passive, deterministic nondepolarizing transformations. Through this framework, the relevant physical quantities, including indices of polarimetric purity, are identified and decoupled. Some decompositions of the whole system into a set of well-defined components are considered, as well as techniques for isolating the unknown components by means of new procedures for subtracting coherency matrices. These results and methods constitute a powerful tool for analyzing and exploiting experimental and industrial polarimetry. Some particular application examples are indicated.

We present a method to accurately measure the birefringence properties of spun fibers using binary polarization rotators. By taking the advantages of binary polarization rotator in polarization analysis, we are able to simultaneously measure both the circular and linear birefringences in a spun fiber with high accuracy. We obtain the circular and the residual linear birefringences of the spun fiber as a function of temperature T to be 3.34 × 10-5.11 × 10T and 8.1 × 10-1.19 × 10T, respectively, with the residual linear birefringence about 4 times less than the circular birefringence. We find, for the first time with the best of authors' knowledge, that the circular and the residual linear birefringences in a spun fiber are highly linear with the temperature, with thermal coefficients of -5.11 × 10 °C and -1.19 × 10°C, respectively, and that the relative changes per °C of the circular and residual linear birefringence are almost identical, with values of -0.152% and -0.147% respectively. We believe that the method and data presented in this paper will be beneficial for making high quality spun fibers, as well as high accuracy fiber optic current sensors.

“…(4) and (6) is how they weigh the different intensity measurements and thus how uncertainties will propagate. If the uncertainty in each of the measurements of intensity is s, then propagation of uncertainties, which is achieved by taking the square root of the sum of squares of each row of each matrix, will yield an uncertainty in the measured Stokes vector of u s ϭ ͑ 1.414s, 1.414s, 1.414s, 1.414s ͒ T (7) for the first matrix and u s ϭ ͑ 0.816s, 1.826s, 1.826s, 1.826s ͒ T (8) for the second matrix. Thus, the choice of using the first row of the matrix in Eq.…”

“…Mueller-matrix polarimeters (sample-measuring polarimeters) or Stokes-vector polarimeters (lightmeasuring polarimeters) have been widely used to measure different polarization properties in optical systems and samples [1,2]. Recently, there have been numerous applications of polarized light including the analysis of polarized light for determining the thickness and refractive index of thin surface films [3], solar astronomy [4], remote sensing (underwater surveying, for example [5,6]), telecommunication systems [7,8], and biology and medicine [9,10]. Imaging polarimetry has also emerged in the last few years to enhance conventional imagery, by providing insightful understanding of the elements that constitute the object based on its polarimetric properties such as birefringence, dichroism, and depolarizing properties [11,12].…”

Improved method for calibrating a Stokes polarimeter

2007

We present a method for calibrating a polarization state analyzer that uses a set of well- characterized reference polarization states and makes no assumptions about the optics contained in the polarimeter other than their linearity. The method requires that a matrix be constructed that contains the data acquired for each of the reference polarization states and that this matrix be pseudoinverted. Since this matrix is usually singular, we improve the method by performing the pseudoinversion by singular value decomposition, keeping only the four largest singular values. We demonstrate the calibration technique using an imaging polarimeter based upon liquid crystal variable retarders and with light emitting diode (LED) illumination centered at 472 nm, 525 nm, and 630 nm. We generate the reference polarization states by using an unpolarized source, a single polarizer, and a Fresnel rhomb. This method is particularly useful when calibrations are performed on field-grade instruments at a centrally maintained facility and when a traceability chain needs to be maintained.
