Abstract: A laser mouse is modified to be a low-cost laser self-mixing Doppler interferometer to perform vibration measurement.The vibration waveform can be retrieved with a simple program,which reduces the cost of hardware and complexity of the measurement system.High-precision commercial vibrometer is included in the vibration measurement to evaluate the performance of the interferometer during the experiment.The experimental results show that the waveform can be retrieved correctly at low frequency,and some possible causes of these errors are analyzed.
