Single Point Laser Doppler Vibrometer (LDV)

 

 

 

 

The single-point Laser Doppler Vibrometer (LDV) is a device which uses a technique able to accurately measure vibration velocity of any kind of structure in a non-invasive way. This overcomes the issues of: mass loading, hazardous areas applications, sensitivity spatial resolution and bandwidth. The LDV system projects a laser beam onto a fixed measurement point, while the surface is moving in the plane of the laser beam. The system thus measures the velocity of the moving surface, although acceleration and displacement options are available in some system.

A typical system would also include a camera tripod for mounting the LDV on and associated computer with application software loaded.

  • Ultra-fast digital signal processing
  • Highest bandwidth up to 10 MHz for real-time digital LDV
  • Excellent resolution up to 2.5 nm/s and 2 pm
  • Easy and quick-change lenses for optimum working distance
  • Compact design optics (interferometer) and electronics (decoder) – in a single housing
  • Variety of different decoders (displacement, velocity and acceleration)
  • Excellent linearity and measuring accuracy
  • High optical sensitivity
  • User-friendly interface with colour touch screen and rotary dials
  • Up to 3 analogue voltage outputs via standard BNC connectors
