Experimental Setup

To have an higher precision for our measurements, we have decided to get, for the same field of view on the same sample of bacteria solution, either a short film segment (from which we can extract frames) and a Microsoft Excel file, which contains a ten seconds interval of values from the photomultiplier output, taken at a 100Hz frequency.

In order to have the same focus for the microscope's oculars, the photocamera and the photomultiplier we have to calibrate our system by changing the position of both camera and photomultiplier.

Finally, we check that the photomultiplier field of view is the same size as the microscope's one: by moving the appropiate diaphragms, we adjust the previously done settings.
