The LV-3800 three-dimensional optical unit is a 3-axis detection optical unit for Laser Doppler Vibrometer (LV-1800/LV-1710/LV-1720/1720A).
This system enables the detection of vibrations occurring in three axes, such as those in structures affected by mass loads where contact-type sensors are difficult to use, as well as vibrations from ultrasonic vibrators and piezoelectric elements, using three-axis laser light. The vibration frequency analysis range is up to 100 kHz, allowing for observation of the velocity, acceleration, and displacement of vibrations occurring in the three axes of the target, as well as various frequency analyses.
Detecting vibrations in three axes with high spatial resolution of laser light
A laser beam with a spot diameter of approximately 30 μm can be used to detect vibrations in three axes.
Even objects affected by mass, such as small cantilevers, can be measured for vibration with high spatial resolution.
Observation and image recording of the detection area are possible coaxially with the laser beam.
By attaching the LV-0181 built-in positioning camera (optional) to the LV-1800 Laser Doppler Vibrometer, accurate positioning and coaxial observation and image recording of the laser beam are possible.
Can be used left, right, or upside down.
The three-dimensional optical unit allows you to change the laser irradiation angle vertically and horizontally. When measuring an object from below, you can also irradiate it from below by installing it inverted.
