Remote sensing of solar-induced chlorophyll fluorescence (SIF) is a rapidly advancing front in terrestrial vegetation science, with emerging capability in space-based methodologies and diverse application prospects. Although remote sensing of SIF - especially from space - is seen as a contemporary new specialty for terrestrial plants, it is founded upon a multi-decadal history of research, applications, and sensor developments in active and passive sensing of chlorophyll fluorescence. Current technical capabilities allow SIF to be measured across a range of biological, spatial, and temporal scales. As an optical signal, SIF may be assessed remotely using highly-resolved spectral sensors and state-of-the-art algorithms to distinguish the emission from reflected and/or scattered ambient light. Because the red to far-red SIF emission is detectable non-invasively, it may be sampled repeatedly to acquire spatio-temporally explicit information about photosynthetic light responses and steady-state behaviour in vegetation. Progress in this field is accelerating with innovative sensor developments, retrieval methods, and modelling advances. This review distills the historical and current developments spanning the last several decades. It highlights SIF heritage and complementarity within the broader field of fluorescence science, the maturation of physiological and radiative transfer modelling, SIF signal retrieval strategies, techniques for field and airborne sensing, advances in satellite-based systems, and applications of these capabilities in evaluation of photosynthesis and stress effects. Progress, challenges, and future directions are considered for this unique avenue of remote sensing.
太阳诱导叶绿素荧光（SIF）的遥感是陆地植被科学中一个快速发展的前沿领域，在天基方法方面具有新出现的能力和多样的应用前景。尽管SIF的遥感——尤其是从太空进行的遥感——被视为陆地植物的当代新专业，但它建立在叶绿素荧光主动和被动传感的研究、应用及传感器开发数十年的历史基础之上。当前的技术能力使SIF能够在一系列生物、空间和时间尺度上进行测量。作为一种光信号，可以使用高分辨率光谱传感器和最先进的算法对SIF进行远程评估，以区分其发射光与反射和/或散射的环境光。由于从红色到远红色的SIF发射可以非侵入性地检测到，因此可以对其进行重复采样，以获取有关植被光合光响应和稳态行为的时空明确信息。随着创新的传感器开发、反演方法和建模进展，该领域的进展正在加速。本综述总结了过去几十年的历史和当前发展。它强调了SIF在更广泛的荧光科学领域中的传承和互补性、生理和辐射传输建模的成熟、SIF信号反演策略、地面和机载传感技术、天基系统的进展，以及这些能力在光合作用评估和胁迫效应方面的应用。本文考虑了这一独特遥感途径的进展、挑战和未来方向。
