UEFA will introduce goal-line technology to Parkhead when Celtiic face Hapoel Be’er Sheva on Wednesday.
The European bosses voted to adopt the Hawk-Eye system and it was installed in all 10 grounds during the recent European Championships in France.
Now it will be used in the Champions League, from the play-off round onwards.
Hawk-Eye is already in use in the English, German and Italian leagues and it uses seven cameras per goal, with control software tracking the ball within the goal area.
Using vision-processing techniques and software, Hawk-Eye indicates whether or not a goal has been scored within one second with a vibration and visual signal on each match official’s watch.
The system will work alongside additional assistant referees who will continue to monitor all activity in and around the penalty area.
UEFA’s chief refereeing officer Pierluigi Collina said: “Goal-line technology and additional assistant referees complement each other perfectly.
“The main task of the additional assistant referees is not to control the goal-line and decide whether a ball has crossed it.
“Rather they are responsible for monitoring everything that is happening in the penalty area overall, aiding the main referee in making important decisions in the box.
“Now, with goal-line technology focused on the goal-line, the additional assistants can focus exclusively on the control of other incidents in the penalty area, the most crucial area of the pitch.”
