Just bought the following IR camera;

For reflectors I am going to use some IR relector tape off a US Army uniform. The new ACU or cat eyes off of a helmet band. This tape only reflects IR light. So with an array of IR lights 12-~20 inches from the tape with a piece of floppy in front of the lense, I figure this should work pretty well.
I'll post later this week if I get it working.
