WebThe new Polytec PSV-400-3D Scanning Laser Vibrometer is the perfect measurement instrument for gathering 3-dimensional vibration data of complex structures. The … WebThe present work investigates the use of a Laser Doppler Vibrometer (LDV) to record valve sounds and characterizes those recordings. An LDV (Polytec PDV-100) was used to measure the normal component of the velocity of the chest wall at 30 points (grid of 6 × 5 points) in each of seven subjects.
