IR interference from fluorescent lights
IR interference from fluorescent lights
(OP)
I am using IR motion capture cameras fo virtual reality application. The lighting in the lab has been switched to fluorescent shop lights would to know if there is a potential for functional interference to the IR signal.

To check, scan the area with a digital camera's electronic viewfinder; IR shows up nice and bright. To check that, use it to look at your TV remote.

There are filters, sheeting, and films to block infrared that are either made for fluorescent lamps (slip-on tubes), or for fixtures (stick on the fixture diffuser), or just rolls of film to custom-make something. 3M is one maker, I'm sure you can find others with the Google machine. That's only if you really experience a problem, which you probably won't.
I agree with Mike, though. Fluorescence emits UV that must be controlled, usually by just the phosphor. Any IR emitted is parasitic and not the result of fluorescence. Perhaps the tiny amount comes from the heat at the small electrodes.

Fluorescent lights have very little NIR content:

Mocap uses highly reflective targets with dark backgrounds. I suggest you consult with someone who's done this before.
