Laser Doppler Surface Velocity Meter
LV-7000 series - Ono Sokki
The LV-7000 series detects speed, uneven speed, distance, length of moving object or rotating object without contact. By contacting with 2 sensors, it enables to calculate difference in velocity/length between the two points in real time and output with 3,000 ppm of accuracy. The frequency response can be expanded up to 20 kHz, which achieves to understand phenomena and evaluate mechanical systems at high speed, efficiently, and accurately. It is useful for evaluation of motor control and behavior measurement, improving parts quality, and reducing loss of material.
