    • Devices for measuring single cell changes in photosynthetic efficiency in algal aquaculture are disclosed that include a combination of modulated LED trans-illumination of different intensities with synchronized through objective laser illumination and confocal detection. Synchronization and intensity modulation of a dual illumination scheme were provided using a custom microcontroller for a laser beam block and constant current LED driver. Therefore, single whole cell photosynthetic efficiency, and subcellular (diffraction limited) photosynthetic efficiency measurement modes are permitted. Wide field rapid light scanning actinic illumination is provided for both by an intensity modulated 470 nm LED. For the whole cell photosynthetic efficiency measurement, the same LED provides saturating pulses for generating photosynthetic induction curves. For the subcellular photosynthetic efficiency measurement, a switched through objective 488 nm laser provides saturating pulses for generating photosynthetic induction curves. A second near IR LED is employed to generate dark adapted states in the system under study.
    • 公开了用于测量藻类水产养殖光合效率的单细胞变化的装置,其包括具有同步通过目标激光照明和共聚焦检测的不同强度的调制LED反照相的组合。 使用用于激光束块和恒流LED驱动器的定制微控制器提供双照明方案的同步和强度调制。 因此,允许单个全细胞光合效率和亚细胞(衍射限制)光合效率测量模式。 通过强度调制的470nm LED为两者提供宽场快速光扫描光化照明。 对于整个细胞光合效率测量,相同的LED提供饱和脉冲以产生光合诱导曲线。 对于亚细胞光合效率测量,切换目标488nm激光器提供用于产生光合诱导曲线的饱和脉冲。 第二个近红外LED用于在被研究的系统中产生暗适应状态。
