Simultaneous reconstruction method for spherical particle optical constant and particle system particle size distribution based on forward scattering multi-angle measurement

The invention relates to a simultaneous reconstruction method for a spherical particle optical constant and particle system particle size distribution based on forward scattering multi-angle measurement and belongs to the technical field of physical property parameter measurement of spherical particles. The simultaneous reconstruction method aims at solving the problems that in an existing conventional method for measuring a spherical particle optical constant and particle system particle size distribution, the measurement results of the spherical particle optical constant and the particle system particle size distribution can not be obtained simultaneously, and the measurement results are not accurate. In the measurement process, two continuous lasers with different wavelengths are used for irradiating the surface of a spherical particle system sample, transmission signals of a particle system in different angles are measured through a detector, and finally the optical constant and the particle size distribution situation of the particle system are indirectly obtained through the inverse problem solving technology. According to the simultaneous reconstruction method, a direct problem and an inverse problem solving model of measurement of the transmission signals of the spherical particle system in different angles is established, and the simultaneous reconstruction technology of the optical constant and the particle system particle size distribution is proposed under the premise that other parameters of the particle system are given. The simultaneous reconstruction method is used for simultaneous reconstruction of the spherical particle optical constant and the particle system particle size distribution.
