| Abstract: | A portable solar-induced chlorophyll fluorescence monitor based on this principle was developed and tested.The instrument uses sunlight as its light source.There are two sets of photoelectrical detectors with the center wavelength at 760 nm and 771 nm respectively and the bandwidth of each detector is 1 nm.Both sets of detectors are composed of an upper detector which are used for detecting incidence sunlight and a bottom detector which are used for detecting reflected light from the canopy of crop.The dete... |
