Laser Doppler Vibrometer
The laser doppler vibrometer can measure up to 16 points of transient or steady-state of vibration and has a multi-beam array generated by AOM. Its features include a field-programmable gate array processor for digital demodulation and novel laser aiming technology. The laser doppler vibrometer is commonly used in the following applications in the industry, aeronautics and space, automotive, hard disk drive diagnostics, micro and nanostructure analysis, civil structure analysis, medical and health care, as well as manufacturing QC.
