ABSTRACT:
Apparatus for spectroscopy of scattering light includes a laser light source, light restricting means for restricting the light scattered by an object, predetermined wavelength selecting means and photon-correlation spectroscopy means for treating the restricted and selected scattering light. This device permits selection of a desired single line of a plurality of spectral lines of the scattering light, and to measure the shape of the spectral line.
