The rebranded UEFA Cup competition is to feature an additional assistant referee beside each goal to help judge whether players have dived in the penalty box and committed fouls at set-pieces, and also determine if the ball has crossed the goal-line.
The system will be unveiled at 24 matches on Thursday with high-profile teams like Ajax Amsterdam, Valencia, AS Roma, Panathinaikos, PSV Eindhoven and Sporting Lisbon involved.
"Things have not improved in refereeing for more than 100 years. I am against video technology because that will take the human face away from the game but this system will help the referee make the right decision," Platini said last month.
"It could be the most significant change in the way the game is officiated for over 100 years."
Nine years ago a low-key experiment was carried out in Brazil's Paulista championship where two match referees - one in each half of the field - took charge of games, each with equal responsibility.
However, soccer's governing body FIFA decided against adopting it.
In February, football's law-making body the International Football Association Board (IFAB) said the experiment could continue at professional level.
Technical experts appointed by the IFAB will monitor the referees' performances to assess the new system and determine whether they enhance their control of the match.
"With the speed of the players today, it's impossible for the referee to keep up," he said. "It's progress and progress is important."
