[0020] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
[0021] The three-dimensional volume scattering function measurement system of the present invention mainly includes: incident light path, receiving light path, scattered light intensity signal acquisition and processing module. The incident light path includes a laser light source 1, a converging lens 2, a nonlinear attenuating sheet 3, and a parabolic spherical mirror 4. , Sample cell 5, receiving light path includes parabolic spherical mirror 4, telephoto lens group 6, 8, diaphragm 7, narrow band filter 9, scattered light intensity signal acquisition and processing module includes photodetector 10 and computer 11. The components of the incident light path are carried by the optical bench and adjusted so that the components are coaxial. The laser output laser 1 is shaped and adjusted in power to converge at the focal position of the parabolic spheric...
