I do that too, if I were them

the physicist in me: if luminescence/activation scales monotonously w shear stress then this is an excellent way to quantify the flow field
DrWurst
of course, it needs correction for activation and relaxation if those time scales are comparable or larger than that of the flow.

The luminescence is a response from the minute algae organisms to being perturbed. It is a momentary response at the individual level …

and has a refractory period of around 12 hours for the algae organism to recharge on its expended luciferin.
