Abstract
A dispensed bead (10) of material is disposed between a sensor pair (14) for monitoring the bead. The sensor pair (14) transmits a beam of light towards the bead of material. A signal is generated which corresponded to the amount of light received. By utilizing this signal, gaps or other discontinuities can be found. This signal can also be used to determine the height of the bead and generate a profile thereof. The signal can be used in a closed loop feedback control system to control the amount of material dispensed from the dispenser.
