Get an overview of Solar-Induced Fluorescence, how the SIFcam system works, and its applications in agriculture, forestry, and plant research.
Solar-Induced Fluorescence is the faint light that every photosynthesising leaf emits under sunlight. It is the most direct optical signal of active photosynthesis measurable from a distance.
NDVI and related indices describe how a canopy looks. SIF measures what it is doing. The difference matters most exactly when it matters most, under stress.
SIFcam measures solar-induced fluorescence in the oxygen A-band from a drone, and turns a flight of snapshot images into a single calibrated SIF map.
Every SIFcam measurement is tied to absolute physical units and cross-validated against established reference instruments such as FloX and HyPlant.
By the time a crop looks stressed, weeks of yield potential are often already lost. SIF detects the physiological decline that comes first.
SIF turns photosynthesis into a measurable trait, giving seed companies objective, high-throughput physiological data across entire field trials.
