Title
(EN) Fluorescence detection assembly for determination of significant vegetation parameters
Abstract
(EN)
According to the invention a basic assembly configuration for determination of relevant vegetation parameters includes a high repetitive pulsed excitation laser (1) for the stimulation of chlorophyll fluorescence, a fluorescence detector (3) including an imaging and separation optic (4, 5), a trigger and delay electronic (6) to adjust the laser and appropriate detector timing and a detector electronic (7), consisting of a signal recording and processing module. An assembly realized according to the invention can be used for determination of relevant vegetation parameters for agricultural, horticultural and greenhouse application.
