An example of the spectral characteristics of tea taken outdoors by the FS-23 hyperspectral camera of FigSpec Imaging

1. Experimental content

A 400-1000nm hyperspectral camera was used to study the phenotype of tea plants

The experimental measurement process is shown in the figure below:

2. Experimental results

In the process of tea growth, the spectral characteristics of the light and backlight sides are very obvious, including the analysis of NDVI index, anthocyanins (1/R(550))-(1/R(700))... Through spectral analysis, further analysis, whether it is necessary to water, fertilize and so on.

3. Conclusion

Through the test of hyperspectral camera, the spectral characteristics are obvious, which plays a certain scientific basis for the study of tea growth, disease and pest stress, water and fertilizer deficiency.
