This code communicates with pixart IR cameras over bluetooth (same cameras used in Wiimotes), and uses the tracking information to control a pair of galvo scanning mirrors using an NI-DAQ.

Controllers for Thorlabs stages were also integrated for accuracy assessment and coordinate system mapping.

A calibration form is provided which shows what each camera sees. I used a square made up of 4 IR LEDs with known separation to generate stereo calibration files.
