| description | A system (1) for detecting microscopic objects located in a flowing fluid. It comprises a lighting system (205, 305) comprising at least one LED diode (605) for supplying light to the flowing fluid; an image capture system (201, 601) configured to capture a sequence of images of the fluid. The image capture system comprises a camera comprising a plurality of pixels. The sequence of images is processed and the presence and shape of microscopic objects is determined. The lighting system (205, 305) is configured to supply high power light pulses having amplitude lo' and very short time duration T ON , the time instant at which said pulses are triggered being synchronized with the time instants at which pixels in the image capture system (601) start to capture an image frame. The amplitude lo' and time duration T ON of the light pulses are controlled by calculating, from the light intensity (I frame ) of each captured image frame, a pulse amplitude setpoint (PAS) and a pulse duration setpoint (PDS) for adjusting respective potentiometers (651, 652) configured to respectively fix the amplitude lo' and pulse duration T ON by executing an algorithm that prioritizes amplitude rises over pulse duration rises. The lighting system (305) comprises an energy loading system (670) configured to make the amplitude requirement and response time of the lighting system (305) independent from the power supply unit. Method for detecting microscopic objects suspended in a flowing fluid. |
