| Design Solution The final prototype used the same setup as prototype two but, changed the measurement device. The device used was a high precision and high sampling rate laser vibrometer. The laser vibrometer provided an enhanced resolution which gave the team a more precise signal on the oscilloscope. Due to the new measuring equipment a block with set screw was incorporated to house the head of the vibrometer laser. The data was again processed in a more evolved Matlab routine. This setup can be seen below.
