Equipped with a high-resolution infrared camera, it realizes accurate detection of every small difference.
Image processing AI software can be selected to enhance analysis accuracy and support integration and online configuration to meet the needs of industrial production line inspection.
Why use hyperspectral imaging for herbal medicine quality control?
The problem of uneven quality and adulteration of Chinese herbal medicines is becoming more and more prominent.
Chinese herbal medicines contain the essence of Chinese medicine, which can prevent and treat diseases as well as rehabilitate healthcare. However, marketization and commercialization demands have brought about problems such as uneven quality and adulteration of Chinese herbal medicines, which not only affect the efficacy, but also may cause harm to the health of consumers, so the quality and safety testing of Chinese herbal medicines is particularly important.
Common methods for authentication of Chinese herbal medicines and their limitations
The authenticity of Chinese herbal medicines can be verified by aesthetic and physical-chemical methods. Appearance authentication is simple but limited in accuracy; physical and chemical authentication is more accurate and objective, but it is complicated, time-consuming and may involve harmful solvents. Each has its own advantages and disadvantages.
Application and Prospect of High Spectral Imaging Technology in the Authentication of Chinese Herbal Medicines
The authentication of Chinese herbal medicines is crucial to public health protection, the Chinese medicine industry and cultural heritage. Hyperspectral imaging is a technology that captures and analyzes information at broad wavelengths, enabling detailed spectral analysis and identification of materials and features. With its rapid, instantaneous and non-destructive detection characteristics, it has shown great potential in the identification of Chinese herbal medicines.
Honghong High Spectrum Inspection System
The Honghong High Spectrum System consists of a high-power infrared light source, tunable wavelength selector, lens and short-wave infrared camera designed for high spectral imaging applications. The infrared light source in the system provides high power output in the 900-1700nm range, while the wavelength selector provides fast, accurate and high-resolution tuning, and the short-wave infrared camera captures the image signals to produce high-quality images as shown in Table 1.
For customers with high spectral imaging needs, we will use the fully automatic tuning wavelength selector FWS-Poly as the core equipment, according to the actual application scenarios, to provide more accurate, high-resolution customized high spectral imaging solutions. This system is suitable for scientific research, industrial inspection and other fields to meet complex imaging needs.

High Performance High Spectrum Camera Captures and Analyzes Broad Wavelength Information of Chinese Herbal Medicines
Hyperspectral imaging technology is capable of detailed spectral analysis and identification of materials and features, based on the principle of hyperspectral camera, which uses multiple optical sensors or optical filters to separate different wavelengths of light and capture images in each wavelength band, quickly obtaining the spatial image of the target in different spectral bands.
Fast, real-time, non-destructive testing
Spatial spectral distribution has the advantages of rapid, real-time, non-destructive detection, etc. It can be used in geological survey, industrial process analysis, scientific archaeology, medical diagnosis, environmental monitoring and other fields, and has been successfully applied to the analysis and identification of gardenia, red ginseng, licorice and other Chinese medicinal herbs.
Programs are safer, more reliable and more comprehensive
High-spectrum imaging technology provides reliable technical support for quality control and safety assurance of Chinese herbal medicines, and can also be combined with other authentication means such as visible light imaging detection, graphic analysis technology, spectral analysis technology, etc. for more comprehensive and systematic authentication of Chinese herbal medicines.

Example of test results
By combining a customized detection module and a spectrometer, the data can be combined and processed to obtain the transmission spectrum, transmittance, start/end wavelength, and other parameters of the filter.

Angelica sinensis and Radix Angelicae Sinensis are commonly used Chinese herbal medicines. They differ significantly in terms of botanical characteristics, growing environment and medicinal efficacy, and therefore there are differences in clinical application and herb collection.
Test result: Taking the 1250nm image as a representative (due to space reasons, this paper only selects the band where the most differentiated image is located for comparison, the same below). The angelized image has black rings and irregular, small black halo distributions, while the solitary image has more black spots and no obvious black rings and black halo distributions, proving that the two have different compositions.

3. Measurement of filter spectra using a single wavelength light source
- The ML light source is used as the illumination source, the wavelength selector is used to select the broadband spectrum, the single wavelength scanning range is set according to the filter spectrum, and each wavelength is recorded by the spectrometer.
- Connect the spectral intensity values of each single wavelength to obtain the spectral curve of the filter, as shown in the black curve on the right.
- In order to provide accuracy, multiple single-wavelength measurements can be taken at different locations on the filter, resulting in multiple black curves as shown above, with the average value taken as the final spectral curve3.
