polarimeter|pəʊləˈrɪmɪtə(r)|
[f. med.L. polāri-s polar (with reference to polarization) + -meter.]
A form of polariscope for measuring the amount of rotation of the plane of polarization, or the amount of polarized light in a beam.
1864in Webster. 1869Eng. Mech. 24 Dec. 357/3 The detection..may be effected with the polarimeter, as pure glycerine has no action upon polarised light. 1897Allbutt's Syst. Med. III. 214 Grape-sugar deflects polarised light to the right, and upon this is based a method of estimation by means of a somewhat expensive instrument called a polarimeter. 1899J. Cagney tr. Jaksch's Clin. Diagn. v. (ed. 4) 162 The rotatory power of each of the four fluids is ascertained by means of the polarimeter.
Hence polarimetric |pəʊlærɪˈmɛtrɪk| a., of or pertaining to a polarimeter or polarimetry; polariˈmetrically adv.; polaˈrimetry, the art or process of measuring or analysing the polarization of light or other electromagnetic radiation.
1864Webster, Polarimetry. 1899J. Cagney tr. Jaksch's Clin. Diagn. i. (ed. 4) 88 The polarimetric test may be applied. Ibid. v. 163 This method..requires a very accurate polarimeter, light polarimetric examinations, and a highly-complicated calculation. 1930[see Foucault]. 1937Jrnl. Org. Chem. II. 431 The mutarotation of glucose was measured polarimetrically, in 200 mm. tubes. 1973Jrnl. Biol. Chem. CCXLVIII. 4165/1 Each solution was then diluted to 12 ml..and the further progress of the reaction followed polarimetrically. 1975Nature 14 Aug. 537/1 In the past, the best-known argument for X-ray polarimetry has been that it is often symptomatic of non-thermal synchrotron-type emission. |
