Polytec non-contact laser vibrometer based on the laser Doppler principle, the core of the device is a high-precision laser interferometer, the laser output from the optical head irradiated to the target to be measured, and at the same time to collect the target's reflected laser light, the interference generated by Doppler shift signals directly proportional to the target's speed, through the controller's decoder processing, the output represents the target speed and displacement of analog voltage.
The laser vibrometer is not only used for conventional vibration measurements, but also plays a special role in the following areas which are difficult to be solved by contact sensors:
●? Devices that cannot have additional mass effects, such as lightweight, flexible, or miniature structures
●? Harsh environments where conventional contact sensors are not readily accessible or are susceptible to damage, such as high temperatures, high pressures, corrosion, radiation, etc.
●? Requires a large number of test points, such as modal measurements of large components, eliminating the need for traditional contact sensors to lay out points and connect wires and other heavy workload.
●? Large amplitude, high g-value vibration and shock measurements, from atomic level weak vibration to millions of g shock
●? Very low or very high frequency vibration measurements
