Title: Improvements in or relating to polarimetric analysis
Inventor: ROUY AUGUSTE LOUISE MARIE ANTO
IPC: G01J4/04
Filed: 1958-10-14
Abstract: 911,365. Photo-electric polarimeters. DAYSTROM Inc. Oct. 14, 1958 [Oct. 15, 1957], No. 32749/58. Addition to 909,961. Class 40 (3). In polarimetric analysis of the kind described in the parent Specification in which a polarized light beam is directed successively through a substance under test and through an analyser, the plane of polarization of the light beam before it enters the substance under test being varied alternately positively and negatively at a constant frequency with respect to the plane of polarization of the analyser, a light beam is alternately directed along two spaced paths, each path comprising means for polarizing the beam positively or negatively. As shown, Fig. 1, a light beam Eo passes through a window 10 in a screen and is intercepted by a rotating disc 13 comprising an odd number of similar radially extending sectors separated by cut-out portions whose angular extent equals that of the sectors. The sectors are mirror-polished on both sides so that the light is alternately reflected at A through a polarizer 16 to a mirror 17, and passed at A via a mirror 20 and through a polarizer 21 to a reflecting sector at D ; in both cases the beam subsequently passes through a container 18 holding the test solution and an analyser 19, to impinge on a photo-cell 12. The planes of polarization of the polarizers 16, 21, are displaced by angles equal in magnitude but opposite in sign (- α, + α) from a reference plane OX which is normal to the axes of the light beams and which coincides with the plane of polarization of the analyser 19. The ratio of the A.C. and D.C. components of the photo-cell output is a measure of the extent of optical rotation of the polarized light beam by the test solution. In a modification, Fig. 3, a single polarizer 16 whose plane of polarization is coincident with that of the analyser 19 is disposed between the light source and point A, and the rotation of the beams + α, - a is effected by adjustable optical wedges 23, 27 placed in the two light paths; the range of adjustment of the wedges may be increased by the addition of plane-parallel quartz plates.
