We uploaded a video of our HALT Vibration Table in Slow Motion.
You can actually see the different axes of vibration. Check it out at http://www.youtube.com/watch?v=l-mBFtFW7Ds.
This video was taken on a Qualmark 3.0 Typhoon table using a high speed video camera.
You are watching approximately 1.5 seconds of video expanded out to over 2 minutes. Look at how the board is flexing and moving in several different directions.
