Scattering system for obtaining multi-faced diffuse reflection information of fruit

Abstract

The invention discloses a scattering system for obtaining multi-faced diffuse reflection information of a fruit. The scattering system comprises a box body, a light source system, an imaging system, a sample delivery system, a sample rotating system and a computer control system located outside the box body, wherein the light source system, the imaging system, the sample delivery system and the sample rotating system are arranged in the box body; the light source system is used for providing a light source for irradiating a sample; the imaging system is used for collecting diffuse reflection information of the light source entering inside the sample to be scattered on the surface; and the sample delivery system and the sample rotating system are used for adjusting the position of the sample and driving the sample to rotate to collect the multi-faced diffuse reflection information of the sample. The hyperspectral scattering system is good in expandability and high in precision, and is capable of quickly and accurately obtaining the diffuse reflectivity of the fruit on a wave band of 400-1,000nm.

Description

technical field [0001] The invention relates to the field of measuring optical characteristic parameters in the study of optical characteristics of biological tissues, in particular to a scattering system for obtaining multi-faceted diffuse reflection information of fruits. Background technique [0002] Spectral analysis technology has been widely used in the field of agricultural product quality analysis. Currently, the analysis methods used are mostly statistical methods, that is, by scanning a large number of sample spectra to establish a correlation model between the sample physical, chemical information and spectral data, and then obtain unknown data. Nutrient physiological information of the sample. [0003] The diversity of agricultural product forms and the complexity of structure bring inconvenience to quantitative analysis. The spectral analysis method avoids the very complicated light transport process inside the tissue. Although the model is simplified, it loses ...

Problems solved by technology

However, the optical fiber of the light source is fixed at a certain angle from the axis of the lens by the fixed bracket, and the angle is adjusted by the nut sliding in the arc-shaped groove, the accuracy is poor, and the distance between the light source and the axis of the lens cannot be adjusted; One-time detection requires manual adjustment to ensure that the distance from the lens remains unchanged, and the process is cumbersome

Moreover, during the scanning process of the object to be measured, the system can only obtain the scattering information facing the scanning system at one time, and the information on the other sides of the object can only be scanned again, which reduces the efficiency of scattering information acquisition, and at the same time cannot automatically collect the measured data. All-round and multi-faceted information of things
