Dear Marietta, We use the APAS system too with 5 cameras. This works OK, the foor does not reflect light. But you might notice that we direct all light towards a white cealing. University of Copenhagen Blegdamsvej 3. We were also mounting force plates underneath the floor.
Carpet surface good for that.
Nike lab seems to be asphalt base and rubber composite material on top - feels like outdoor track runway. Concrete with epoxy finish. Epoxy is designed to have low reflectivity, good resistance and wear characteristics. Put in a cable so wires are not all over the place. Here at Duke, we went with a Mondo track surface, which is similar to our outdoor runway track.
