Paper Abstract

A developed in situ measuring system uses light emitted diodes (LED) and laser diodes(LD) as light sources is employed for the recording of algae chlorophyll fluorescence induction kinetics (Kautsky-effect). Photosynthesis activity as an important parameter is obtained in the system which measures the chlorophyll fluorescence yield. Minimal fluorescence is excited by the brief but really weak light pulses from LED as measure light while photosynthesis is happened, variable fluorescence which means there is energy conversion through photosynthesis is also excited by a LED but the beam is more stronger, LD induced saturation fluorescence stands for maximum fluorescence. The system could works for alga chlorophyll photosynthesis activity continuous measure in situ through efficiently mechanical and optical design.
