Description

Precision Vibration Measurement with Laser Doppler Vibrometry

The LV-S01 Laser Doppler Vibrometer from Hoyang Instrument Limited offers a non-contact solution for measuring vibration velocity, displacement, and acceleration. By leveraging the laser Doppler frequency shift effect and advanced laser interferometry, this instrument delivers accurate, real-time data across a wide range of applications.

Product Series

Our product line includes two versatile configurations to meet diverse measurement needs:

Single-Point Helium-Neon Laser Vibrometer

This model measures vibration along the laser direction with high precision. It features automatic focusing, remote focusing, and focus memory functions, ensuring ease of use and repeatability. With strong anti-interference capability, extremely high resolution, and a wide dynamic range, it is ideal for laboratory and industrial applications.

Full-Field Scanning Laser Vibrometer

Designed with a modular architecture, this system can be equipped with various decoders to suit different measurement scenarios. It achieves a maximum measurement speed of up to 12 m/s, making it suitable for high-velocity vibration analysis. The system also offers robust anti-interference performance and exceptional resolution.

Key Features

  • Non-contact measurement: No mass loading on the test object, preserving its natural vibration behavior.
  • High resolution: Extremely fine sensitivity for detecting minute vibrations.
  • Wide frequency range: DC to 3 MHz or DC to 25 MHz options, covering static to high-frequency dynamic measurements.
  • Long working distance: From 0.35 m up to 20 m, providing flexibility in setup.
  • Automatic and remote focusing: Simplifies operation and enhances measurement consistency.
  • Focus memory: Retains focus settings for repeated measurements.
  • Strong anti-interference: Reliable performance in challenging environments.
