The invention discloses a
system for measuring a three-dimensional
volume scattering function of a microparticles in water. The
system comprises a parabolic spherical reflector, a
sample pool, a
telescope group, a photoelectric
detector and a computing
processing unit, wherein the
sample pool is arranged in a reflector cavity of the parabolic spherical reflector, the center position of the
sample pool is located in a parabolic spherical focal point of the reflector cavity of the parabolic spherical reflector, incident light is converged at the reflector cavity focal point position, incident to a parabolic spherical surface after being subjected to
particle scattering in the sample
pool, transformed into parallel
scattered light, received by the photoelectric
detector after passing through the
telescope group, and transmitted to the computing
processing unit for
processing, and thus, the three-dimensional
volume scattering function of the
microparticle can be obtained. The invention further discloses a method for measurement by utilizing the
system. According to the invention, the problem of detection deviation generated when a plurality of detectors are used for detecting the
volume scattering functions of different angles is avoided, the acquired image is good in uniqueness and high in
contrast ratio and can be completely fixed in a work process, and the measuring stability is good and the measuring speed is high.
