多功能植物光合表型成像测量系统

 

多功能植物光合表型成像测量系统PlantExplorer采用创新的多光谱叶绿素荧光/可见光成像技术，利用的LED技术、CCD技术、通信技术，实现了对植物表型的创新测量，可以在获取RGB成像、叶绿素成像、花青素成像的同时，获取叶绿素荧光成像（成像面积53cm x 53cm）。系统包括带光学滤光轮的CCD成像系统、聚焦系统、嵌入式高亮度红光LED、光谱白光LED、多光谱LED、嵌入式电脑和触摸屏。由于采用一个CCD加滤光轮的组合，使得能够在像素水平上进行图像叠加计算。

 

多功能植物光合表型成像测量系统PlantExplorer包括三个版本：标准版PlantExplorer、高级版本PlantExplorer^Pro和适合高达120cm植物的版本PlantExplorer^Pro+。三个版本都可以选配GFP和/或RFP成像模块（需在购买时指出，不可后续升级），其中PlantExplorer可以在购买后，再后续升级成PlantExplorer^Pro。
