LIGHT SCATTERING MEASURING APPARATUS

摘要

A rotary table (11) on which a half mirror (8) and an optical detector (10) are placed is turned continuously around a first rotary shaft (A) passing through a sample (S) to set it to a desired scattering angle. At the same time, a rotary reflector (7) is turned a predetermined angle so that the reference light (LR) is constantly directed toward the half mirror (8), and the half mirror (8) is also turned around its own axis a predetermined angle so that the direction of the scattered light (LS) at the outgoing side of the half mirror (8) and that of the reference light (LR) agree with each other. This enables the reference light and scattered light to be combined at an arbitrary scattering angle, and the Doppler shift in the direction of the scattered light to be observed.
