Application area introduction:

Outdoor crop growth monitoring: Place the Lambda hyper-spectral imaging system on a tripod or elevated platform,Used to monitor the growth of crops,Such as crop nitrogen content, chlorophyll, biomass, etc,It can also be used to monitor crop diseases and soil fertility,So as to provide technical support for agricultural fine management.

Real-time detection of river water quality: lambda hyper-spectral imaging system was placed on the water quality detection platform,Such as tripod, tower, etc.More than 10 kinds of water quality parameters can be detected in real time,Such as total phosphorus, total nitrogen, chlorophyll a, suspended solids, PH, chemical oxygen demand, ammonia nitrogen, dissolved oxygen, etc.

Plastics separation: lambda hyper-spectral imaging system was mounted on a dark box system equipped with a light source,Such as PE, PP, PS, PC, PA, PU, PET, PVC, POM and ABS, etc.

Identification of real and counterfeit banknotes

Lambda hyper-spectral imaging system was used to obtain the hyper-spectral images of real and counterfeit banknotes,Real and counterfeit banknotes can be identified by spectral analysis and texture analysis.

Tree species identification and growth monitoring: The leaves of different tree species were collected and placed in an indoor dark box,Lambda hyper-spectral imaging system was used to acquire its hyper-spectral imaging data,By spectral analysis and texture analysis,The distribution of agronomic indicators of leaves and leaves of different tree species can be distinguished,It provides a theoretical basis for distinguishing different tree species and monitoring their growth.

Fruit and vegetable sorting: With the improvement of living standards,More and more attention has been paid to the quality and safety of fruits and vegetables,It is important to quickly and effectively identify fruit rot, damage and maturity.For example, the internal rot that causes black and white spots on the surface of fruits, and the bruise and damage caused by transportation and other reasons,Thus seriously affect the health of consumers,Therefore, it is of great significance to quickly and effectively identify fruit black and white spots, bruises and fruit maturity.Lambda hyper-spectral imaging system can be used to quickly and accurately detect black and white spots on fruit skin caused by internal decay, skin damage during transportation, fruit maturity and sugar content, etc。Realize the rapid sorting of fruits and vegetables.

 Biomedicine:Lambda hyperspectral imaging system can be used in the biomedical field for tongue coating detection, wisdom tooth examination, skin detection, mole recognition, etc.

Figure 12 shows the moisture content distribution of tongue coating of k0074, k0082 and k0090 patients. It can be seen from Figure 11 that K0074 has a high moisture content and more drooling, which indicates that the patient has no spirit and is one of the manifestations of chronic kidney disease
