PlantScreen Imaging sensors

PlantScreen TM Imaging Sensors are complete integrated solutions for non-invasive analysis of plant specific patterns of absorption, emission and reflection. Digital trait assesment sensors are based on analysis of wide range of electromagnetic radiation wavelength bands: visible range of spectra is detected by RGB cameras for structural and color analysis, hyperspectral cameras in visible, near-infrared and short wavelength infra-red range of spectra are used for reflectance-based analysis of plants, thermal imaging cameras are optimized for leaf temperature and stomata conductance analysis, kinetic chlorophyll fluorescence imaging sensors for analysis of plant photosynthetic performance.

RGB and Morphometric Imaging Wide range number of features linked to plant growth and development can be extracted from digital colour RGB imaging or 3D scanning technology, when connected to the automatic software analysis. RGB digital imaging applied in high resolution is used for in-depth analysis of plant morphology, architecture and colour index analysis.

Industrial high performance cameras with a Gbit Ethernet connection are mounted on robotic arm together with the white LED light source to ensure high speed data transfer and precise color separation. Cameras with high-sensitivity CCD-sensors, high-resolution and broad dynamic range are used.

Kinetic chlorophyll fluorescence Imaging Chlorophyll fluorescence is popular technique in plant physiology used for rapid non-invasive measurement of photosystem II (PSII) activity. PSII activity is very sensitive to range of biotic and abiotic factors and therefore chlorophyll fluorescence technique is used as rapid indicator of photosynthetic performance of plants in different developmental stages and/or in response to changing environment. Systems developed by PSI monitor fluorescence kinetics in pulse-amplitude modulated mode , which provides a wealth of information about a plant's photosynthetic capacity, physiological and metabolic condition, as well as its susceptibility to various stress conditions.

The advantage of chlorophyll fluorescence measurements over other methods for monitoring stresses is that changes in chlorophyll fluorescence kinetic parameters often occur before other effects of stress are apparent. The method is non-invasive, and the spread of inhibition can be observed and quantified with time. Heterogeneity in the location of inhibition is easily seen and quantified when using imaging systems to measure chlorophyll fluorescence. Chlorophyll fluorescence kinetics measured in the PlantScreen TM Phenotyping Systems provides a wealth of information about a plant's photosynthetic capacity, physiological and metabolic condition, as well as its susceptibility to various stress conditions.
