LV-1800 Series Laser Doppler Vibrometers

The LV-1800 non-contact type Laser Doppler Vibrometer uses newly designed interference optical system and has achieved improvement of detection sensitivity by 20 dB compared to the conventional models. The built-in positioning camera makes it easy to check the target by laser beam irradiation. The LV-1800 can perform amplitude velocity measurements in a wide range of fields that are difficult with a contact type vibration sensor; small actuator using piezoelectric element, cell phones and digital camera with MEMS (Micro Electro Mechanical Systems), inverter an other devices in an EV/HEV. By using the LV-1800 with an FFT Analyzer, it is possible to visualize not just vibration but also the state of the vibration.
