Multipoint laser Doppler vibrometry with single detector : principles, implementations, and signal analyses
A 20-point laser Doppler vibrometer with single photodetector is presented for noncontact dynamic measurement. A 5 × 4 beam array with various frequency shifts is generated by a 1:55 μm distributed feedback laser and four acousto-optic devices, and illuminating different points on vibrating objects....
