One#Characteristics of the system
A key feature of Fluoresens 10 is its optical path integrity. By using dedicated optical fibers and rotating optical mechanisms to alternately capture sky and vegetation radiation for each spectrometer, the collected signals do not require internal switches or splitters for reorientation. Therefore, the radiation intensity from the fiber to the spectrometer remains constant throughout the entire process, which is the basis for accurate measurement of SIF. The spectrometer manufacturer recommends recalibration only when the fiber optic connection is physically separated, or once a year while maintaining the connection.
Spectral response calibrated using HL-3P-CAL lamp. The response curves of the same fiber before and after reconnection (fiber 1 and fiber 1 *) and using different fibers (fiber 2) demonstrate how subtle changes in the optical path introduce measurement errors, highlighting the importance of a complete optical path.

The spectrometer is maintained at approximately -10 ° C through a dual thermoelectric cooling (TEC) design, which reduces dark noise. Stable temperature control can enable the measurement system to operate stably for a long time during external temperature fluctuations and continuous unmanned operation.

The core of Fluoresens 10 isCR1000X series data collectorIt can achieve all measurement, time synchronization, and system control functions. Researchers can add the necessary biometeorological sensors based on their research objectives, thereby expanding their monitoring capabilities for multivariate ecosystems.
The Fluoresens 10 system uses intelligent control algorithms to automatically optimize integration time based on environmental light intensity. Under high irradiance, a complete measurement cycle takes about four seconds, while under cloudy or low light conditions, the measurement cycle may be extended to about one minute. The dynamic adaptation characteristics of the system enable high-frequency sampling of canopy fluorescence and reflectance, capturing rapid physiological change signals.
The calibration and diagnosis of the spectrometer are integrated into the Fluoresens 10 system. Both spectrometers can be calibrated in situ using the built-in RTMC real-time monitoring and control software. This feature provides users with flexibility in calibration, maintaining measurement accuracy and ensuring cross seasonal repeatability, ensuring the stability of the system in long-term field work.
To accurately explain the relationship between daylight induced chlorophyll fluorescence (SIF) and carbon flux, it is necessary to maintain spatial consistency between optical and flux measurements. The Fluoresens 10 achieves 180 degree field of view measurement through cosine corrected front optical components. Ensuring the matching degree between SIF footprint and vortex related system observation source area has improved the comparability between SIF and carbon exchange.
Two#Application advantages
By integrating Fluoresens 10 with vortex related systems, researchers are able to quantify the correspondence between daylight induced chlorophyll fluorescence (SIF) and total primary productivity (GPP), thereby gaining a deeper understanding of light energy utilization efficiency and carbon assimilation dynamics. These data contribute to the improvement of terrestrial biosphere models and enhance the ability to predict carbon cycle feedback on climate change.
FluoreSens 10's measurement of SIF can reveal plant physiological stress responses before visible symptoms appear. The changes in SIF intensity and spectral shape can indicate drought, temperature stress, or nutrient limitation. Combined with vegetation indices, it can provide a comprehensive diagnostic framework for plant health monitoring and stress response research.
Ground observation SIF plays a crucial role in verifying fluorescence data obtained from satellite remote sensing (such as GOSAT, TROPOMI, OCO-2, FLEX). The continuous observation of Fluoresens 10 can provide necessary reference data for algorithm model development and scale matching research.
