Claim 0:
1. An apparatus for remote detection of plant growth dynamics, the apparatus comprising:
an excitation LED (light emitting diode) module comprising at least one LED, each LED configured to emit an excitation light in response to an excitation control signal, the excitation light having an emitted light spectrum;
a detection module comprising a photodetector configured to detect an initial chlorophyll a fluorescence (“ChlF”) light and an excited ChlF light from a plant species, the photodetector further configured to convert 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; and
a controller module coupled to the excitation LED module and the detection module, the controller module configured to provide the excitation control signal to the excitation module, to capture the initial and excited detection electrical signals from the detection module and to determine chlorophyll fluorescence data based, at least in part, on the initial and excited detection electrical signals, 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;
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.
