Abstract
A laser detection system including at least one laser device projecting a light curtain, and a controller is provided. The controller includes a processor and non-transitory, processor-readable memory including executable instructions that, when executed by the processor, cause the controller to receive a signal from the at least one laser device, the signal including an interference point of an object with the light curtain, and distance data indicating a distance between the interference point and the at least one laser device, determine a location at which the object enters the light curtain based on the distance between the interference point and the at least one laser device, and identify an item of a plurality of items located in an area behind the light curtain and corresponding to the location at which the object enters the light curtain.
