If one assumes that the holes as well as the beams' cross-sections are rectangular and the illuminations homogeneous, then the current [I.sub.hom] produced by either of the photocells will be proportional to the breadth b of the light spot measured on the surface of the photocell when the axle is rotating, i.e., [I.sub.hom] ~b.
Assuming that the reduction in the transmitted light intensity (i.e., photocell voltage increase) due to the addition of particles (tracer or second component) in the light path is directly related to the total light intensity transmission factor, we can say that:
