Measuring non-contact vibration can be done very easily by connecting Laser Vibrometer to PULSE,
Brüel & Kjær’s Multi-analyzer
The OMETRON Vibrometer is used for non-contact measurement of vibration velocity on various surfaces, including those at extreme temperatures, underwater, or in high radiation environments. It is ideal for applications where mounting a vibration transducer is impractical or undesirable, such as on delicate structures, soft materials, or in clean rooms.
