Limitations!• Piezo transducers are 3.7 cm in diameter…too big!
• Suspending guitar can be tricky…does not hang the
same way twice
• Time constraints

Developments• Calibration of piezo transducers- correlating voltage
with space to develop plots w/ space dimensions as
z-axis
• Map out using more points with smaller transducers
• Understand better the DAQ graphs
• Laser Holography?
