VibroScan. Measurement without limits—from macro to micro
From a few centimeters to several meters—this is the range our customers are already working within today using the VibroScan QTec®, whether on a vehicle body or a compact individual component. The microscope extension now opens up a third dimension. Using the same measuring head and without switching systems, you can measure down to the micrometer range. From an elephant to a fly’s leg—measure without limits using a single system.
From macro to meso to micro range, we have the right solution for every dimension:
Why microscopic vibrations matter for large structures
Disruptive vibrations in smartphones, ECUs, or medical devices often originate from tiny causes – an actuator, capacitor, or bond wire in the micrometer range. A seamless measurement solution allows users to zoom in precisely down to component level, without switching systems, adopting a new data format, or additional training effort.
Three factors make this possible: fine laser focusing, high-precision positioning in the micrometer range, and microscope optics with shallow depth of field for accurately separating closely spaced structures.
Practical examples in this video range from MEMS microphones to a bee's antenna. The advantage over dedicated microscope systems: the overall context of the assembly remains visible, with stable signal quality even on rough, dark surfaces.
Macroscale: large structures, real-world behavior
In the macro range, VibroScan QTec captures the dynamic behavior of large structures in vehicle bodies, brakes, machine frames, or aerospace components. Depending on the application, the SWIR laser or the HeNe laser, in combination with the QTec® multi-path interferometer, delivers precise data even over long distances and on difficult surfaces—without the need for time-consuming surface preparation.
Area-wide scanning with FEM-like resolution reveals vibration modes and natural frequencies of entire assemblies and identifies vibration hotspots. With RoboVib and RoboVib Bench, complex 3D tests are completed in hours rather than days.
Webinar: Spin the blade, not the risk
See how non-contact laser vibrometry reveals the vibration and strain behavior of blisks, turbine blades, and turbocharger components. Shorten test times, accelerate design validation, and gain more reliable insights into the dynamic behavior of your components.
Meso range: subcomponents in detail
In the meso-scale range, the focus shifts to critical subcomponents such as actuator housings, printed circuit boards, and sensor mounts. QTec® ensures an optimal signal-to-noise ratio even when using a mix of materials. This means fewer averages, shorter measurement times, and more measurement points exactly where it counts.
This allows local effects to be correlated with overall behavior and FE models to be refined in a targeted manner.
Non-contact vibrometry for meso-components and microstructures
From cm² down to the µm scale—discover how VibroScan QTec precisely characterizes the dynamic behavior of small, embedded structures such as camera modules, MEMS microphones, and bonding wires, while seamlessly extending into meso- and micro-scale measurements with compatible optical add-ons.
Micro range: finest details, spot size < 2 µm
The microscope extension allows standard microscope objectives to be mounted on the VibroScan close-up unit with a spatial resolution of less than 2 µm. Using the VibroScan QTec Neo and a visible helium-neon laser, you can precisely measure bond wires, MEMS cantilevers, and microactuators—even through media such as water.
Especially on printed circuit boards or actuators, you’ll encounter a mix of different surfaces. Unlike conventional vibrometry, QTec® guarantees an optimal signal-to-noise ratio even in these cases. The smaller the object, the more you’ll notice this difference.
Microscope Extension for VibroScan
Extend your VibroScan to the microscale.
The new Microscope Extension for the VibroScan Scanning Vibrometer enables high-resolution, non-contact vibration measurements from macro to microscale using a single measurement system.
One sensor head, one software—no need to switch systems, no setup required. This is ideal for your measurements in the fields of MEMS, consumer electronics, and medical technology.
Measure across scales
Analyze vibrations, acoustics, and dynamic behavior across scales using vibrometry. Measure biomedical samples, electronic components, and microstructures with light—free from mass loading and over a wide frequency range.
With VibroScan, now you can zoom in on the smallest details to capture deflection shapes for model validation, assess frequency response, and determine key parameters.
VibroScan QTec addons extend the range of applications to meso- and even microstructures, while specific software features enable precise target alignment and high resolution for meso components.
Special microscopic instruments (MSA) resolve an order of magnitude more structural details, but limit the field of view.
Measure what matters at any scale and without compromise.
