In order to further reduce the production of low-quality grapes, reduce the EU's subsidies to the wine industry, and improve the international competitiveness of EU wines, in 2011 the EU launched the EU research project PREMVM (improving grape quality with multiparametric field analysis of grapes and leaves in vineyards, Improve the quality of the grapes by field multi-parameter analysis of grapes and leaves in the vineyard).
Chlorophyll fluorescence technology is one of the most important non-destructive measurement techniques for detecting plant growth and stress. It is not only suitable for measuring leaves, but also for measuring chlorophyll-containing fruits. At the same time, during the ripening process, the pigments and biochemical components such as sugar, chlorophyll, polyphenols, nitrogen and anthocyanins will change accordingly. Reflective spectroscopy is the best tool for nondestructive testing of these components. 
The project initially used WINEPEN chlorophyll fluorescence and spectrometers developed by PSI (Photon Systems Instruments) specifically for this project. 
The results show that there are significant changes in the chlorophyll fluorescence spectrum in different growth stages. The reflectance spectra of green and red fruits are very different, indicating that their pigment composition and related biochemical components are greatly different. This provides a scientific basis for quantitative analysis of grape growth dynamics and quality identification. 
As technology advances, the instruments used in this type of research have evolved from handheld chlorophyll fluorescence and spectrometers to chlorophyll fluorescence imagers and hyperspectral imagers. Researchers can measure multiple fruits and even whole grape ears at the same time. When performing blade measurements, it is also possible to obtain comprehensive data and corresponding images of the entire blade, rather than the limited data that only the previous handheld instrument can only measure one point of the blade. The modern plant phenotypic imaging analysis technology represented by FluorCam chlorophyll fluorescence imaging technology and Specim hyperspectral imaging technology declares that plant and crop phenotypic research has entered a more comprehensive and accurate two-dimensional era from the traditional one-dimensional era. 
Modular plant phenotypic analysis technical solution recommended:
1. Basic plan: FP110 handheld chlorophyll fluorescence instrument + RP410 handheld plant reflectance spectrometer or manufacturer custom WinePen
2. Advanced program: FluorCam chlorophyll fluorescence imaging system + Specim IQ handheld hyperspectral imager
3. Advanced solution: FluorCam multispectral fluorescence imaging system + FX10/FX17 portable hyperspectral imager or SisuCHEMA hyperspectral scanning imaging analysis system

It can prevent some medicine or blood from splashing on the face, thus protecting the eyes. This kind of glasses is generally used in conjunction with masks and surgical caps to fully protect the doctor's head.
[Functions of medical eye masks]
1. Prevent blood, potion and other liquids that cause damage to the skin from causing unpredictable damage to the eyes.
2. It can prevent the impact of objects on the eyes during close surgery.
3. The inner space of the eye mask is large enough for doctors who wear myopia glasses.
4. The breathability must be good, generally there are vents
