Originally, it was our intention to perform interferometry to analyze the diamond vibration.  After several attempts to use the interferometer, it was determined that the vibration amplitude was simply too high to perform interferometry.  Instead, a direct imaging technique was used to analyze the diamond vibration.  An interesting phenomenon occurred when the direct imaging device was used.  The reflected spot entering the camera lens created an artifact known as a lens flare.  Typically lens flares are undesirable, but in our case, the lens flare movement directly correlated to the movement of the reflected beam spot on the lens surface.  By careful calibration, the pixel movement on the image versus the angular displacement of the diamond surface was determined.
