The technology, which is already in place at US and Australian Opens, will rely on cameras mounted around Centre Court and Court One that will capture 3D images of any disputed line call.

Large screens positioned so that they are viewable by all spectators in the courts will show exactly where the ball lands.

The introduction of Hawk-Eye at Flushing Meadows and Melbourne Park has been deemed a success but Wimbledon will be the first major grass tournament to employ the system.

All England Club chief executive Ian Ritchie believes grass requires a different process for consulting the technology compared to other surfaces.

At the US and Australian Opens players are allowed two unsuccessful challenges during a set and one more in a tie-break.

Ritchie said: "We're looking at the options available to us at the moment. It's unlikely we'll implement unlimited challenges.

"We're considering the possibility of an extension but there's a balance to strike with the continuity that was evident in the US and Australian Opens.

"Different situations can arise on grass courts where the service is especially important. We're looking at the alternatives - maybe a limited extension to the number of challenges. But unlimited challenges are not an option."
