Embodiment Construction

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0034] Common point light source spectral diffusion detection systems such as figure 1 shown. The point light source emitted by the light source performs diffuse reflection, refraction, absorption, etc. on the surface of the sample 2, and the spectral image of the surface of the sample 2 is obtained by collecting the spectral information generate...

Abstract

The invention provides a diffusion detection system. The system comprises a CCD (Charge-Coupled Device) camera, an imaging spectrometer, a lens, a line light source, a sample, a two-dimensional translation stage and a computer, wherein the sample is arranged on the two-dimensional translation stage; a light signal emitted by the line light source irradiates to the sample surface; the acquired light signal is collected by the lens, the imaging spectrometer and the CCD camera respectively and is converted into an electric signal, and the electric signal is transmitted into the computer so as to acquire a detection spectrum; and a light source line emitted by the line light source is perpendicular to the slit direction of the imaging spectrometer. The diffusion detection system disclosed by the invention can be applied to the field of nondestructive testing of agricultural and animal products and the like, and the technical problem that a large measuring error is caused because light spot deformation is generated on the sample surface in a single point spectrum diffusion detection system in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a diffusion detection system. Background technique [0002] In recent years, with the development of spectroscopic technology, more non-destructive, more convenient and more efficient detection methods and methods have appeared in the quality inspection of agricultural products. Compared with the traditional method, the detection speed is improved and the subjective influence of man is reduced. [0003] Spectroscopy is a non-destructive detection technique that uses the properties of light absorption, scattering, reflection, and projection of a substance to determine its composition. Therefore, for the same substance to be detected, there are still different spectral detection methods. It is also an important detection method in spectral detection to use the diffusion mode of light on the surface of the material to extract the scattering characteristics of the material to det...
