.
主要功能
l 成像功能：对Ft、Fo、Fm、Fv/Fm、F、Fm’、Y(II)、Y(NO)、Y(NPQ)、NPQ、qN、qP、qL、ETR、Abs.、NIR、Red等至少17种参数进行成像分析。测定调节性能量耗散Y(NPQ)，反映植物光保护能力，测定非调节性能量耗散Y(NO)，反映植物光损伤程度。
l 程序测量功能：可程序测量荧光诱导曲线、快速光曲线和暗弛豫，也可手动测量；在测量过程中能自动分析所有荧光参数的变化趋势
l AOI功能：可在测量前或测量后任意选择感兴趣的区域（AOI），程序将自动对选择的AOI的数据进行变化趋势分析，并在报告文件中显示相关AOI的数据。所有报告文件中显示的数据都可导出到EXCEL文件中。
l 成像异质性分析功能：对任意参数任意时间的成像，可在图像上任意选取两点，软件自动对两点间的数据进行横向异质性分析，并可导出到EXCEL文件中。
l 成像数据范围分析功能：对任意参数任意时间的成像，可分析任意两个荧光数值之间有多少个像素点，多少面积（cm2）。
l 突变株筛选功能：可跟据成像结果快速筛选光合、产氢/油、抗逆（抗盐、抗旱、抗病等）等突变株。
l 吸光系数测量功能：快速测量叶片的吸光系数。吸光系数测量光源： 16个红光（650 nm）和16个近红外（780 nm）LED，用于测量植物叶片或藻类样品PAR吸光系数。
