FLATNESS TESTER FOR SHIPPING TRAYS

摘要

A method for testing the flatness of shipping trays. The method consists of generating an optical field, placing an optical detector in communication with the optical field, actuating the optical field to a platen, having a shipping tray on the platen and monitoring an interaction of the shipping tray with the optical field, and using a detector to detect the magnitude of the interaction of the shipping tray with the optical field to measure the shipping tray's flatness and determining if the tray's flatness is within a specified tolerance.
