Problems solved by technology

At the same time, there are also imaging systems that combine hyperspectral reflection, interaction, and diffuse transmission modes, but the three-mode combined system reported now is intermittent and non-continuous (Hu, et al., Postharvest Biology and Technology, 2016, 115: 122-131), this discontinuous three-mode hyperspectral system will bring a large workload when used in the laboratory, and it is not suitable for actual production applications
At present, there are no reports on the integration of four or more hyperspectral imaging modes into one system for continuous imaging.

Abstract

The invention discloses a turn-back continuous multi-mode hyperspectral imaging system, which comprises a fixed support part, a transmission control module, a light source module, a spectral imaging module and a control and data processing center module. By the multi-mode hyperspectral imaging system, point scattering, reflection, transmission and interaction imaging modes can be achieved, so that a plurality of quality and safety indicators of a to-be-tested sample can be simultaneously achieved; and a relatively accurate decision is provided for experimental study and industrial production. Furthermore, a fluorescent hyperspectral imaging technology can be achieved by exchanging a light source; and the turn-back continuous multi-mode hyperspectral imaging system can also be achieved by combining a microscopic imaging technology. A multispectral chip is etched by a stroboscopic light source or a semiconductor on the basis of the turn-back continuous multi-mode hyperspectral imaging system, so that a corresponding multispectral imaging system can be built; and the industrial high-flux detection requirements are met.

Description

technical field [0001] The invention relates to a hyperspectral imaging detection technology, and more specifically relates to a novel hyperspectral system with reentrant continuous multi-imaging modes. Background technique [0002] Hyperspectral imaging technology has been widely used in agriculture (Kandpal, et al., Sensors and Actuators B-chemical, 2016, 229: 534-544), food (Kamruzzaman, et al. al., Meat Science, 2016, 116: 110-117), art (Mounier, et al., Color Research and Application, 2016, 41: 302-307) and medicine (Nie, et al., Journal of Biomedical Optics, 2013 , 18(9), literature number: 096001) and other fields have been widely used. [0003] However, many hyperspectral imaging systems currently use single-mode imaging technology for research or application. Due to the simple structure of hyperspectral reflectance imaging technology, many of the applied invention patents (application number: 201010117612.0) and reported practical applications (application number:...
