ABSTRACT:
A method and apparatus for monitoring the laser marking of a bar code label which has been laser marked onto the end of a nuclear fuel tube for unacceptable depth penetration of the heat affected zone. The average gray level value of the bar code label positioned on the end of the nuclear fuel tube is compared with a predetermined standard. In the method disclosed, a bar code label positioned on the surface of the nuclear fuel tube is optically sensed and a set of discrete digital values representative of the depth penetration of the heat affected zone is generated. The average digital value representative of the bar code label is calculated and the average digital value compared to a predetermined standard.
