POLRADS: polarization radiance distribution measurement system.
While the upwelling radiance distribution in the ocean can be highly polarized, there are few measurements of this parameter in the open ocean. To obtain the polarized in-water upwelling spectral radiance distribution data we have developed the POLRADS instrument. This instrument is based on the NuRADS radiance distribution camera systems in which linear polarizer's have been installed. By comb...
متن کاملAn Upwelling Radiance Distribution Camera System, NURADS
We have built a new instrument to measure the in-water spectral upwelling radiance distribution. This instrument measures the radiance distribution at six wavelengths and obtains a complete suite of measurements (6 spectral data images with associated dark images) in approximately 2 minutes (in clear water). This instrument is much smaller than previous instruments (0.3 m in diameter and 0.3 m ...
متن کاملPolarized radiance distribution measurement of skylight. II. Experiment and data.
Measurements of the skylight polarized radiance distribution were performed at different measurement sites, atmospheric conditions, and three wavelengths with our newly developed Polarization Radiance Distribution Camera System (RADS-IIP), an analyzer-type Stokes polarimeter. Three Stokes parameters of skylight (I, Q, U), the degree of polarization, and the plane of polarization are presented i...
متن کاملPhase measurement of a spatially varying polarization distribution
The measurement of the polarization and phase distributions of a wave field is an often posed problem [1,2]. Usually, the polarization is determined by measuring the Stokes parameters, but without access to the phase. Phase shifting interferometry (PSI) may be used to determine the phase, but without considering the polarization as a measurand. In this work, we will propose an interferometric a...
متن کاملQuantum key distribution based on phase encoding and polarization measurement.
A one-way quantum key distribution scheme based on intrinsically stable Faraday-mirror-type Michelson interferometers with four-port polarizing beam splitters has been demonstrated that can compensate for birefringence effects automatically. The encoding is performed with phase modulators, but decoding is accomplished through measurement of the polarization state of Bob's photons. An extinction...
