Laser Doppler Vibrometer LV Series

Precision Vibration Measurement at Microscopic High Frequencies

Techris Systems proudly supplies the Ono Sokki Laser Doppler Vibrometer (LV Series), a cutting-edge, non-contact vibration measurement system designed to detect microscopic and high-frequency vibrations with unmatched sensitivity and accuracy.


Advanced Non-Contact Vibration Detection Using Laser Doppler Technology

The LV Series Laser Doppler Vibrometer employs sophisticated laser Doppler techniques to measure vibration velocity without physically contacting the target. This non-invasive method prevents any loading or interference on delicate or small-scale objects, ensuring precise measurement even on microscopic vibrations.

The latest model, the LV-1800, features a newly designed interference optical system, boosting detection sensitivity by 20 dB over previous models. Its built-in positioning camera allows easy visual confirmation of the laser beam’s target spot, simplifying setup and increasing measurement reliability.


Key Features:

  • Non-contact laser Doppler measurement eliminates mechanical loading on the test subject.
  • Detects microscopic and high-frequency vibrations with exceptional sensitivity.
  • Built-in positioning camera for precise target alignment.
  • Wide detection frequency range suitable for delicate or small-scale objects.
  • Compatible with FFT analysers for comprehensive vibration analysis and visualisation.

Applications Across Diverse Fields

The LV-1800 is ideal for measuring vibration in applications where traditional contact sensors are impractical or impossible, including:


  • Small actuators with piezoelectric elements
  • MEMS devices in cell phones and digital cameras
  • Inverter and motor components in Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV)
  • Any delicate components requiring precise vibration velocity measurements


Using the LV-1800 combined with an FFT Analyzer allows engineers to not only measure vibration amplitude and velocity but also visualize the vibration state, providing deeper insight into product performance and potential issues.


Technical Specifications (LV-1800):

  • Measurement Method: Laser Doppler non-contact vibrometer
  • Frequency Range: Up to several MHz (model-dependent)
  • Sensitivity Improvement: +20 dB over conventional models
  • Built-in Camera: Yes, for laser spot positioning
  • Non-Contact: Completely load-free measurement
  • Compatible with: FFT analysers and data processing software
