Refractometry and Polarimetry [PDF]
, 1994 When a ray of electromagnetic radiation strikes a flat surface at an angle, the ray may be bent upward (reflected) or bend downward (refracted) as illustrated in Fig. 27.1. Notice that the ray does not go straight through the material.

Stochastic Scattering Polarimetry
Physical Review Letters, 2008We introduce the general concept of stochastic scattering polarimetry and demonstrate that the anisotropic polarizability of a scattering object can be obtained by analyzing the statistical moments of polarimetrically measured intensity distributions.

Abstract Polarimetric data for 4179 Toutatis were obtained during 23 nights from 10 December 1992 to 29 January 1993 at wavelengths of 0.41, 0.46, 0.54 and 0.70 μm. It is found that: (1) no peak of linear polarization P occurs, at least in our available data, between a phase angle α = 0.3° and 101.3°; (2) the inversion angle, where P = 0, is about 20°

A summary of results of observations of the polarization of Mars shows that surface pressure determinations from these data have not yielded satisfactory results in spite of the extensive number of observations available. It is suggested that the difficulty lies mainly in the neglect of radiative components resulting from a combination of diffuse ...

We address the magnetic field structure of solar pores. The data were obtained at the Gregory Coude telescope at Izana using the ATI CCD camera system to observe pores with three spectral lines: one magnetically sensitive line, recording all 4 Stokes profiles, and two g = 0 lines where only the intensity profiles were measured.

Moller and Mott polarimeters have been compared concerning their measurement accuracy in a dedicated "spin dance" experiment. The results obtained with the different polarimeters at vastly different energy ranges were in agreement with each other within the given systematic uncertainties of a few percent.

Generalized channeled polarimetry
Journal of the Optical Society of America A, 2014Channeled polarimeters measure polarization by modulating the measured intensity in order to create polarization-dependent channels that can be demodulated to reveal the desired polarization information. A number of channeled systems have been described in the past, but their proposed designs often unintentionally sacrifice optimality for ease of ...

Polarimeters were developed to measure the polarization of the proton beam at RHIC in relative scale through the asymmetry measurement of the elastic proton-carbon scattering. Recoil carbon ions with kinetic energy of 400 ≤ E ≤ 900 keV were detected by silicon strip detectors installed at 90° with respect to the beam. The absolute polarization is given

Icarus, 1982
The polarization of Pluto has been measured for a range of solar phase angles from 0.8 to 1.8 deg. A mean linear polarization of 0.29 + or - 0.01% (error of the mean) was found. No dependence of both the amount of polarization and position angles with rotational phase or solar phase angle could be detected.

Photometry and Polarimetry [PDF]
, 1977 The most widely used photometric system, photographic B and V, has serious systematic problems that are not generally recognized. The photographic sensitivity bands do not match well with the corresponding photoelectric sensitivity bands; and as a result, the photographic systems each have a colour coefficient of the order of 0.1 (B–V) with respect to ...
