An optical sugar cane yield monitor that consist of a row of optical sensors mounted in the elevator floor of the harvester in such a way that when combined with the appropriate electronics, software, and connections, the system measures a duty-cycle type reading of billet depth on the slats that is related to the amount of sugar cane flow through the harvester. The sensors are inserted in the elevator floor in such a way that they run in the material flow and self-clean with the normal souring of the elevator floor.
