The full-back made the switch from French club Agen in May to sign a two-year deal in Ulster, joining South African compatriots Ruan Pienaar and fellow new signing Wiehahn Herbst at the Irish province.
Ludik's first chance to impress will be in the away trip to Scarlets on the first weekend in September, as Ulster look to go one further and reach the GUINNESS PRO12 final this season.
And the 27-year-old, who is quickly getting used to life in Belfast, promises to leave nothing out on the pitch in an Ulster jersey.
"At the moment it is all about getting fit and learning how the coaches want me to play and where they want me to fit into the team," Ludik told Ulster's official website.
"When I get onto the field I will give everything as a player. I can't wait to get out there.
"The facilities are the best that I have seen. They are the next level. It is such a privilege just to be there and to work out - it is awesome.
"People have been really friendly. We are still trying to find our way about but everyone that we have spoken to has been so helpful.
"We want to see what Ulster is all about. Next week we are planning to take an open top bus tour to see a bit more of Belfast."
