Leaf-scale chlorophyll fluorescence LiDAR development and preliminary results for field measurements
Résumé
Outdoor measurement of chlorophyll fluorescence at the leaf scale as a reliable and fast probe of plant photosynthetic activity is a challenge in agronomy. A better understanding of the stationary and transient heterogeneity of photosynthetic activity within the canopy will require concomitant leaf scale measurements targeting different strata, since irradiance varies depending on leaf orientation and position within the canopy. As a contribution to the emergence of such tools, this communication presents the development and preliminary measurements of chlorophyll fluorescence LiDAR, with an measurement range of 60 cm and a footprint of 30 cm2. It was performed indoors on maize.
