Microorganism Tracking System
Continuous observation of individual motile microorganisms is difficult, since their swimming speed is fast compared with their diameters. Microorganisms can quickly go out of the range of static measurement instruments, such as the field of view of optical microscopes.
To solve this problem, a microorganism tracking system using a high-speed vision system has been developed. This system tracks a freely swimming microorganism within the field of an optical microscope by moving a chamber of target microorganisms based on high-speed visual feedback.
