| 英文摘要 | As a plant functional optical signal, the Solar Induced Chlorophyll Fluorescence (SIF) has a unique advantage in evaluating plant photosynthesis. In recent years, high -quality research results have been achieved with SIF data as the core. However, how to evaluate SIF accurately and quantitatively itself is a huge challenge. We propose a novel transmissive hyperspectral imaging spectrometer specifically designed for SIF observation named HSIS-SIF. It works in the full fluorescence emission band of 650 - 800 nm, with a field of view of 20 degrees , Spectral resolution better than 0.3 nm and spatial resolution of 1mrad, and the key Prism -Grating dispersion element composed of the prism and volume phase holographic transmission grating enables the spectrometer to achieve higher energy collection ability and light transmission efficiency while ensuring the excellent optical performance mentioned above. At the weakest SIF signals, the Signal -to -Noise Ratio of the system is still better than 100. High -resolution imaging experiments with the prototype were conducted for mapping the plant canopy SIF, Normalized Difference Vegetation Index, and Near Infrared reflected radiation. The results indicate that our design has excellent optical performance and can perform high -precision SIF detection tasks, as well as providing additional vegetation indices, which has enormous application potential. |
