  • Polarimeter - an overview | ScienceDirect Topics
    The MICROwavelength POlarimeter (Fig 7) is a single-view multi-spectral airborne polarimeter built at LOA in the 2000s with support from CNES This instrument is the precursor of the OSIRIS instrument and operates in five bands centered at 490, 670, 865, 1600, and 2200 nm
  • Polarimeter - an overview | ScienceDirect Topics
    A polarimeter is a device used to measure the rotation of plane polarized light caused by optically active compounds in a solution, such as in the determination of sucrose and reducing sugars in fruit and fruit products AI generated definition based on: Encyclopedia of Analytical Science (Second Edition), 2005
  • Polarimetric and fluorescence spectroscopic based classification of . . .
    A linear detection response is observed by both polarimeter and fluorescence spectrometer in a wide range 0–0 28 g ml of sugar These results depict that PLRA polarimeter is novel, remote, precise and cost-effective for quantitative determination of optically active ingredient in the host solution
  • Polarimeters from bulky optics to integrated optics: A review
    The polarimeter is a scientific instrument which can analyze the relative polarization properties of light, such as degree of polarization, orientation angle, ellipticity angle, extinction ratio and circular dichroism Polarimeter is a basic measuring instrument in optical communications, polarization imaging and other related applications
  • Mott electron polarimetry - ScienceDirect
    A polarimeter based on spin depen- dences in low-energy (- 10 eV) scattering from a mag- netized iron surface has been demonstrated [61] This offers high efficiency e, > 1 x 10-3, but is again sensi- tive to the surface condition and input beam parame- ters
  • Rotating dual-retarders to correct polarization measurement error for . . .
    The polarimeter is a weak polarization system, and the small rotation range is conducive to searching the optimal solution Therefore, we set the fast axis angles of the two retarders as −20° to −25° and 40° to 50° respectively
  • A compact full Stokes polarimeter - ScienceDirect
    The polarimeter consists of a Quarter Wave Plate (QWP), film polarizer, photodiode, high speed hollow core brushless DC (BLDC) motor, and a printed circuit board (PCB) containing all the required electronics Fig 1 shows the CAD model of the developed polarimeter The hollow core BLDC motor is used to rotate the wave plate
  • A Compton polarimeter using scintillators read out with MPPCs through . . .
    The next section details tests of the polarimeter components, i e scintillators, MPPCs and the ASIC used to process the MPPC signals In Section 3, the performance of a prototype polarimeter is reported for both an unpolarised and a polarised ∼ 50 keV beam of photons We are able to make a clear detection of the modulated counting rate for a
  • Development of simultaneous imaging polarimeter for asteroids
    The test-observations of the prototype polarimeter have been carried out in December 2003 and January 2004, mounted on the 101 cm telescope at Bisei Astronomical Observatory, Okayama, Japan In the observations, unpolarized and polarized standard stars were observed to measure an instrumental polarization and its uncertainty
  • A generalized land surface reflectance reconstruction method for . . .
    The Particulate Observing Scanning Polarimeter (POSP) sensor onboard the GF5–02 satellite is a single-view multispectral polarimetric scanner It has a field of view of ±50° with a nadir resolution of 6 4 km, and a swath width of ∼1850 km The orbital altitude of GF5–02 is 705 km, and the local time of the descending node is 10:30 a m
