Abstract

A laser marking system with beam deflection verification for marking products and product packaging (20) with information such as batch numbers and date codes. The laser coding system includes a computer controlled laser (28), together with a computer controlled laser beam deflection system, to directly write on product packages or products by burning the marking thereinto or through a coating thereon. The laser beam deflection system includes deflection system position sensors (56 and 58) to provide outputs indicative of the then present position of the beam. These deflection system outputs are correlated with the deflection system command signals to detect any abnormal deviations between the commanded positions and the actual positions indicative of a deflection system failure. A sensor is also provided for sensing the laser intensity to verify proper laser operation and to allow automatic laser power control measurement of the laser beam intensity by deflection of the beam to an out-of-range position for product marking, further verifying deflection system operation, as well as verifying laser operation and providing a signal for laser power control (70). Various features, such as the ability to verify operation while writing on moving product packages, and alternate embodiments, are disclosed.
