Cameras

A good structured light camera will have a high framerate, high resolution, and CCD sensor (in order to capture contiguous bursts of time), in that order of importance.

Song Zhang has mentioned using the JAI/PULNiX TM-6740CL (640x480, 180 FPS) in his work, which can cost up to $2,000 USD without a lens. It requires a separate capture card.

Possible alternatives to the JAI/PULNiX camera are Point Grey's Dragonfly Express or Grasshopper, (both 640x480, 200 FPS) which can be around $1,300 USD without a lens.

Also consider Prosilica's GE680 (640x480, 200 FPS) and GC640 (659x480, 200 FPS), both running over gigabit ethernet.

Not that much information is available on using Elphel cameras at a high speed, but the NC353L has been said to run at 640x480, 108 FPS, with higher framerates at lower resolutions, and lower framerates at high resolutions.

An extremely cheap alternative to all of the above cameras is the Playstation 3 Eye. The ps3eye can run comfortably at 640x480, 60 FPS or 320x240, 100 FPS. HIgher frame rate experimental modes are also available. Alex Popovich has developed a small SDK to help with interfacing to the eye.

Projectors

DLP projectors can effectively triple the theoretical maximum framerate of your system by using the consecutive red, green, blue layers/filters as separate frames.
