    Is the fan shaped beam horizontal or virtical ? On my origional water drop detection suggesting a laser pointer, assumed a single detector which gives a target of about 1/10 in; not an easy target to hit reliably with drops falling 15 ins. Are you suggesting 5 detectors side by side, horizontally? How small of a hole can drops fall thru with out touching the sides of the hole?
