Abstract
Scanners, methods, and computer storage media having computer-executable instructions embodied thereon that process variable sized objects with high package pitch on a moving conveyor belt are provided. The scanners are laser scanners that include at least two laser diodes, sensors, and field programmable gate arrays processors. The at least two laser diodes have different focuses. Each diode generates a laser beam when excited by an activation signal and an appropriate modulation. The sensors within the laser scanner device measure light reflected from a target on the objects. The processors toggle activation among the at least two laser diodes based on measurements sensed from the light reflected from the target.
