Construction: The polarimeter consists of a monochromatic source S which is placed at focal point of a convex lens L. Just after the convex lens there is a Nicol Prism P which acts as a polariser. H is a half shade device which divides the field of polarized light emerging out of the Nicol P into two halves, generally of unequal brightness.
The Astro-2 Spacelab consisted of three unique instruments – the Hopkins Ultraviolet Telescope (HUT), the Ultraviolet Imaging Telescope (UIT) and the Wisconsin Ultraviolet Photo-Polarimeter Experiment (WUPPE). These took measurements from objects within the Solar System as well as individual stars, nebulae, supernova remnants, galaxies and ...
The Wisconsin Ultraviolet Photo-Polarimeter Experiment (WUPPE) was a space telescope with a 50cm diameter mirror for spectroscopy and polarimetry in the ultraviolet spectral range. It was used in conjunction with other telescopes on the shuttle missions STS-35 (ASTRO-1 in December 1990) [ 1 ] and STS-67 (ASTRO-2 in March 1995).
A simple polarimeter to measure this rotation consists of a long tube with flat glass ends, into which the sample is placed. At each end of the tube is a Nicol prism or other polarizer. Light is shone through the tube, and the prism at the other end, attached to an eye-piece, is rotated to arrive at the region of complete brightness or that of ...
Two waves differing by a quarter-phase shift for one axis Creating circular polarization using a quarter-wave plate and a polarizing filter. For a quarter-wave plate, the relationship between L, Δn, and λ 0 is chosen so that the phase shift between polarization components is Γ = π/2.
Auguste Laurent (14 November 1807 – 15 April 1853) was a French chemist who helped in the founding of organic chemistry with his discoveries of trichloroethylene, ...
Here a 1 and a 2 denote the amplitude of the wave in the two components of the electric field vector, while θ 1 and θ 2 represent the phases. The product of a Jones vector with a complex number of unit modulus gives a different Jones vector representing the same ellipse, and thus the same state of polarization.
Sir David Brewster KH PRSE FRS FSA Scot FSSA MICE (11 December 1781 – 10 February 1868) was a Scottish scientist, inventor, author, and academic administrator. In science he is principally remembered for his experimental work in physical optics, mostly concerned with the study of the polarization of light and including the discovery of Brewster's angle.
