Abstract
The present invention relates to a fluorescence sensor for measuring microalgae and a method of operating the same. The fluorescence sensor for measuring the microalgae includes a fluorescence measurement unit including a light emitter configured to irradiate excitation light onto a measurement region and a detector configured to measure fluorescence emitted from the measurement region, an algae control unit configured to form a node and an antinode of an ultrasonic standing wave in the measurement region to control an algal density, and a signal processing unit configured to calculate the algal density using fluorescence intensity signals according to an operation mode of the algae control unit.
