Multiplex sensor is a hand-held multiparametric optical sensor developed by Force-A. The sensor is a result of 15 years of research on plant autofluorescence conducted by the CNRS (National Center for Scientific Research) and University of Paris-Sud Orsay. It provides accurate and complete information on the physiological state of the crop, allowing real-time and non-destructive measurements of chlorophyll and polyphenols contents in leaves and fruits.
Technology
Multiplex assesses the chlorophyll and polyphenols indices by making use of two attributes of plant fluorescence: the effect of fluorescence re-absorption by chlorophyll and screening effect of polyphenols.
The sensor is an optical head which contains:
Optical sources (UV, blue, green and red)
Detectors (blue-green or yellow, red and far-red (NIR))
Applications
Alongside with other data, Multiplex is designed to provide input for decision support systems (DSS) for a range of crops, including:
Fertilization applications
Crop quality assessments (nitrogen status, maturity, freshness and disease detection)
As a standalone sensor, Multiplex is a tool for rapid collection of information concerning chlorophyll and flavonoids contents of the plant to be applied on ecophysiological research.
