Single-Point-Laser vibrometers

A single-point laser vibrometer measures vibration velocity, displacement, or acceleration at a single defined point. In contrast, scanning or 3D vibrometers capture vibrations across multiple points or simultaneously in several spatial directions.

Single-point systems are ideal when a specific measurement point needs to be examined in detail — for example, for resonance analysis, material testing, or functional verification of individual components.

A single-point vibrometer is used when individual structures or components need to be examined with high precision. This is especially relevant in quality assurance, research, or test bench environments where targeted point measurements are required.

Typical applications include vibration analysis of machine components, materials, medical devices, civil structures, or MEMS components.

The vibrometer directs a laser beam onto the surface of the test object. From the frequency shift of the reflected light caused by the vibration (Doppler effect), the system calculates the motion of the measurement point.

This method is completely non-contact and requires no physical attachment of sensors to the object.

Because the system measures without physical contact, it does not affect the mass of the test object. This results in unaltered, accurate measurement data — even for sensitive, hot, or moving components.

In addition, there is no installation effort as with conventional sensors, and measurements can be performed quickly and with high repeatability.

Yes. Through manual or automated positioning, the vibrometer can measure sequentially at different points. In combination with multiple devices or fiber-coupled sensor heads (e.g., SMART Multi-Fiber), multiple points can also be captured simultaneously.

This allows the system to be flexibly adapted to the specific measurement task.

Single-point vibrometers offer digital and analog interfaces such as Ethernet, USB, or BNC, allowing them to be directly integrated into test benches, measurement systems, or automated production processes.

Trigger inputs and outputs make it possible to seamlessly integrate the systems into existing test benches and automation workflows.

In principle, measurements can be taken on almost any surface — including dark, rough, or shiny materials. The SWIR laser technology (1550 nm) used in Optomet systems ensures stable signal quality, even on challenging surfaces.

The possible measurement distance depends on the system type. Standard devices of the SMART and CLASSIC series cover distances from a few millimeters to several meters.

Specialized models such as the CLASSIC Nova-Xtra enable measurements over distances of up to 300 m — for example, for structural testing or outdoor inspections.

The CLASSIC series offers robust, clearly structured systems designed for established measurement tasks in laboratory and industrial environments. Data acquisition is digital but intended for single-device operation or sequential multi-point measurements — in multi-fiber configurations, the measurement points are switched one after another.

The SMART series expands this concept with a fully integrated system architecture. Multiple devices can be directly linked and automatically synchronized, enabling multi-point measurements to be captured simultaneously. Setups can be flexibly extended and combined into modular measurement systems, including a shared time base and integrated analysis functions.

Both series are based on the same optical measurement principles but differ in system architecture, expandability, and the way multi-point measurements are implemented.

Optomet systems are operated using SMART Lab (SMART series) or OptoGUI (CLASSIC series). Both applications provide remote control, data acquisition, and real-time analysis of measurement data.

The data can be further processed via open interfaces (e.g., MATLAB, LabVIEW, or Python) or integrated into existing systems.
