Optical mixing devices for the spectrum analysis of the scattered light from polymer solutions are reviewed. This newly developed technique has somedifference from the usual spectrometer in principle, and is able to carry an extremely high resolving power up to 1014. For the application to the polymer problem, however, there are still many points to be improved. In the present review, after giving a theoretical consideration, problems on the signal-to-noise ratio and the “depolarized light mixing” technique for the detection of the rotatory diffusion broadening are described in concentration. It must be emphasised that the technique has a unique field of observation which might be paired with the dielectric dispersion measurements. It could cover a low frequency region of 101_??_107 Hz far below the coverage of theusual Raman spectrometer.
