Description

The MotionGo MVS is a miniaturized laser Doppler vibrometer for non-contact vibration measurements — ideal when minimal sensor mass and installation effort are required or access to the measurement point is limited. An integrated guidance laser enables quick target alignment, making the MVS particularly well suited for mobile or frequently changing setups. Automatic zoom and autofocus keep measurements stable across a wide distance range without the need for repeated manual readjustment.

For integration into test and automation environments, the MotionGo MVS provides measurement signals in parallel via digital and analog outputs. Trigger and synchronization interfaces ensure clean timing references in distributed measurement setups and multi-sensor applications. With its rugged, compact design, the MVS is well suited for both industrial use and embedded applications — wherever precise vibrometry is expected to “just work”.
