Scanning Vibrometer
The world’s first SWIR Scanning vibrometer: Compact, high-end, and groundbreaking.
SCANNING LASER DOPPLER Vibrometry
Optomet pioneered the world’s first short-wave infrared (SWIR) laser-based scanning laser Doppler vibrometer which eliminates the need for surface treatment and produces the highest quality data through superior measurement sensitivity.
State-of-the-art Scanning laser vibrometry
Optomet pioneered the world’s first short-wave infrared (SWIR) laser-based scanning laser Doppler vibrometer which eliminates the need for surface treatment and produces the highest quality data through superior measurement sensitivity.
Maximum sensitivity due to the largest optical aperture
The Optomet scanning laser Doppler vibrometer has the industry’s largest optical aperture, maximizing the collection of reflected laser light. This ensures the highest possible measurement sensitivity even at points with minimal laser backscattering.
Measurements on any surface
By combining the ultra-high sensitivity of the Optomet scanning laser Doppler vibrometer with the superior signal quality of the SWIR laser technology, even surfaces with minimal optical reflectivity and at the greatest measurement distances can be accurately measured. Test objects with varying surface reflectivity and complex geometries are measured by the Optomet scanning laser Doppler vibrometer in one measurement process, without the measurement surface having to be prepared with reflective film.
User-friendly measurement software
The OptoSCAN scanning laser vibrometer software is the industry’s most user friendly and modern user interface which enables even inexperienced users to efficiently obtain precise measurement data. For details see Software / OptoSCAN.

Laser vibrometer measuring and data acquisition software
Our Scanning Laser Vibrometer can either be used in scanning operation mode using the OptoSCAN software but also in single-point operation mode using the OptoGUI Software to manage the vibrometer settings, start the measurement, and perform the data analysis. Both operation modes and programs can even be used simultaneously.
OptoGUI
OptoGUI is an extensive and intuitive software for remote control, data acquisition, and data analysis when working in single-point mode. Data transfer is realized via a loss-free digital Gigabit Ethernet connection.
OptoSCAN
OptoSCAN is an extensive and intuitive software for remote control, data acquisition, and data analysis when working in scanning mode. Data transfer is realized via a loss-free digital Gigabit Ethernet connection.

Available Decoders
A wide variety of high-performance real-time decoders are available for the evaluation of the interferometric measuring signals. The Optomet UltraDSP technology enables the measurement of frequencies up to 25 MHz (for Single-Point Operation Mode) and vibrational velocities up to 30 m/s, displacements can be resolved to less than 100 fm. All vibrometers incorporate a velocity decoder. Displacement and acceleration decoders are optionally available. Numerous measuring ranges per decoder ensure that measurements can always be performed with the optimum sensitivity.
Decoders can be easily retrofitted or upgraded. Start with a basic system and adapt the capabilities of the measuring instrument as required later on. This requires no return of the instrument to the factory and no waiting times for your production or research project. The table below provides an overview of the configuration options. We will also be happy to assist you in the selection of the best decoder for your measuring task.
