Abstract

The invention discloses a method and a device for measuring optical parameters of red jujube tissues by polarized scattering, relate to the field of methods for measuring optical parameters of agricultural product quality, and solve the problems that the influence of surface thin-layer textures and refractive index distribution characteristics on the spectral polarization state is neglected in the non-destructive detection of red jujube quality, so that high detection accuracy cannot be obtained. The method mainly measures the optical parameters of red jujube tissues by polarized scattering,and comprises the steps: performing theoretical simulation on an equivalent scattering model of different structural characteristics of red jujube to obtain theoretical control characteristic parameters; measuring physical and chemical indicators of red jujube slices in different periods, and marking a corresponding red jujubepolarized scattering diagram to obtain a correspondence between opticaltissue parameters and micropore scale characteristic parameters; performing multi-angle polarized reflection and polarized transmission detection on the slices to obtain actual optical tissue parameters; and correcting the deviation between the theoretical control parameters and the actual optical tissue parametersto obtain an optical parameter model of the red jujube tissues for judging the quality of red jujube in actual test.

Description

technical field [0001] The invention relates to the technical field of a method for measuring optical parameters of agricultural product quality, in particular to a method and device for measuring optical parameters of jujube tissue by polarization scattering. Background technique [0002] In the quality inspection of jujube, non-destructive testing methods are usually used. The conventional spectral non-destructive testing method adopts multiple scattering correction MSC, and the method of standard normal variable transformation SNV improves stability while reducing accuracy. However, since jujube is a natural product with a complex structure, The distribution of components is not uniform, and its internal organization can be equivalent to a scattering medium in which scattering units of different scales are randomly distributed; since the refractive index distribution of scattering units of different equivalent scales varies with wavelength, the polarization state and direc...
