Abstract
A differential laser Doppler biospectrometer for monitoring microbiota movement in a medium, which, preferably is quiescent. One of the laser beams is shifted in frequency to enable monitoring of small movement data velocity and/or direction). Average size of individuals and growth rate of the total number of organisms in suspension can be obtained. Exogenous stimuli, such as electric and magnetic fields, trace chemical additions or EM radiation are provided at selected times in the natural rhythm circadian cycle of the microbiota, and several such stimuli can be applied simultaneously. The measurement system is so sensitive that it can detect movement changes due to very weak energy stimuli transmitted to microbiota free to move in an established zone. In addition, holographic recordings of the microbiota can be made.
