FIELD: physics. ^ SUBSTANCE: device consists of focusing optics, mixing plate, diaphragm, a source of reference radiation, photodetector, filter, subtracting unit, multiplier, unit for extracting the doubled root, detector, unit for comparing values of factors and determining alphaP, unit for determining the sign of alphaP, unit for controlling polarisation of the source of reference radiation, and a unit for determining alphaC. The mixing plate, diaphragm and the photodetector are connected in series in the path of the reference radiation from the source of the reference radiation. A valve, the focusing optics, mixing plate, diaphragm and photodetector are connected in series along the path of the analysed radiation. ^ EFFECT: increased accuracy of measuring the angle of the polarisation plane of optical radiation. ^ 1 dwg |
