FloX植物荧光监测系统是一种独特的仪器，能够连续观察叶绿素荧光。它可以测量极高分辨率的光谱数据，但它的建造可以承受永久性室外安装的危险。

它代表了多工辐射计辐照度计（MRI）、SFLOR盒和SIF系统等原型的演变，这些原型是由Jülich研究中心和米兰比科卡大学环境动力学遥感实验室合作开发的。FloX的基本程序基于SPEY（Forschungszentrum Jülich，IBG-2：Plant Sciences）。

 

FloX专门设计用于在自然光照条件下被动测量叶绿素荧光。因此，该设计经过优化，以在信噪比、光谱分辨率和快速采集时间方面实现最大效率。该系统的核心Ocean Optics公司的QEPro光谱仪，覆盖红色/近红外区域（650–800 nm）。这是叶绿素荧光发射的光谱范围，并使用两个大气氧吸收带（分别位于689 nm和760 nm处的O2B和O2A）进行测量。FloX的向上和向下通道允许测量太阳辐照度和来自树冠的反射辐射。为了保持稳定的暗电流水平，光谱仪被嵌入一个温度控制的外壳中。由于两个通道信号的精确自动优化和高性能光吞吐量，信噪比最大化。

特点：

1、红外/近红外诱导叶绿素荧光长期监测

2、FILIX柔性规范协议

3、快速测量周期

4、全自动测量协议

5、低功耗
