Abstract: The method utilizes the physical phenomenon known as dispersion of the optical rotation. After passage of linearly polarized electromagnetic radiation through the optically active environment (rotator), with the rotating power characterized by a parameter p, and then through the analyzing polarizer, the function R(p) can be measured. For the given active medium and the relative orientation of polarization planes of the input light beam and the analyzing polarizer, R(p) has an unambiguous relation with the spectrum I(lambd) of the analyzed radiation (lambd stands for wavelength) and allows its unambiguous determination by special mathematical methods. In devices based on the above mentioned principle a linearly polarized collimated beam of analyzed radiation propagates through the optical rotator then passes through the analyzer and strikes a single-channel or multi-channel detector which measures R(p) as a function of the parameter p. Finally the desired spectrum is calculated from the known functional relation between the measured rotogram R(p) and I(lambd).

Abstract: The proposed method employs physical phenomenon of optical dispersion rotation for determining light spectral characteristics. Polychromatic linearly polarized radiation passes through a medium, which bends polarization plane of spectral components thereof in dependence on wavelength. After subsequent passage through an analyzing polarizer a dependence of light intensity S({phi}) at the angle {phi} that is included by the analyzing polarizer with the analyzed light polarization plane is measured. The light intensity is in mathematical relationship with the analyzed radiation spectrum I({lambda}) ({lambda} denotes the wavelength) and makes it so possible to determine spectral characteristics of the analyzed radiation. In apparatuses operating on the above-described principle a collimated polarized beam of the analyzed radiation passes first through an optical element exhibiting dispersion of optical rotation i.e. a rotator (4), further through an analyzing polarizer (5) and after representation it is detected by a suitable detector (7) that is capable to measure the function S({phi}) in dependence on the angle of the polarizer angular displacement, whereby from this function the spectrum parameters I({lambda}) are subsequently determined.
