Optical detection system for nondestructive detection of pesticide residue on surface of fruit and vegetable

Abstract

The invention provides an optical detection system for nondestructive detection of pesticide residue on the surfaces of fruits and vegetables. The system includes a Raman laser detection system and a rotary positioning device. The rotary positioning device is for positioning and rotating the samples to be detected; and after the rotary positioning device stops rotating the samples to be detected, the Raman laser detection system conducts optical detection on the samples to be detected. In this way, the Raman laser detection system can detect multiple directions of the samples, at the same time, due to the Raman laser detection system conducts optical detection after the rotary positioning device stops rotating the samples to be detected, aliasing of signals collected by the Raman laser detection system can be avoided to ensure the accuracy of detection.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an optical detection system for non-destructive detection of pesticide residues on the surface of fruits and vegetables. Background technique [0002] my country is the world's largest producer and consumer of fruits and vegetables. In the international trade of agricultural products, due to the lack of practical testing technology to ensure the quality and safety of fruits and vegetables, the export of agricultural products such as fruits and vegetables in my country is facing huge challenges. Some major importing countries of agricultural products have set high standards, used technical barriers and green barriers, which have caused repeated setbacks in my country's fruit and vegetable exports. The problem of pesticide residues in fruits and vegetables has received more and more attention, which has restricted the rapid and healthy development of the fruit and vegetable indu...

Problems solved by technology

[0004] However, in the process of realizing the present invention, the inventor found that the optical detection system in the prior art cannot automatically realize the multi-point detection of the sample to be detected, resulting in the low efficiency of the multi-point detection of the sample to be detected
