Claim 8:
9. A method for remote detection of plant growth dynamics, the method comprising:
providing, by a controller module, an excitation control signal to an excitation LED (light emitting diode) module;
emitting, by at least one LED included in the excitation LED module, an excitation light in response to the excitation control signal, the excitation light having an emitted light spectrum;
detecting, by a photodetector included in a detection module, an initial chlorophyll a fluorescence (“ChlF”) light and an excited ChlF light from a plant species;
converting, by the photodetector, the detected initial ChlF light into an initial detection electrical signal and the detected excited ChlF light into an excited detection electrical signal, the excited ChlF light emitted from the plant species in response to receiving the excitation light;
capturing, by the controller module, the initial and excited detection electrical signals from the detection module, the excitation control signal comprising an excitation pulse comprising a pulse train defined by a plurality of excitation pulse parameters, a respective value of each of the plurality of excitation pulse parameters is related to a growth dynamic of the plant species; and
determining, by the controller module, chlorophyll fluorescence data based, at least in part, on the initial and excited detection electrical signals;
wherein the excitation LED module and the detection module are configured to be positioned remotely from the plant species, and wherein the chlorophyll fluorescence data represents a growth characteristic of the plant species.
