Remote Vibration Measurements on Wind Turbines
Preventative maintenance, or condition monitoring of wind turbines is often done with the aid of contact vibration transducers that are attached at various positions along the drive shaft. Laser vibrometers are powerful tools for remote, non contact vibration monitoring of large engineered structures with a long standoff distance. The measurements are made easily from the ground.

Measuring the Dynamic Response of Solar Panels
Unlike traditional contact transducer measurement techniques, the measurement of solar panel dynamic properties with a scanning vibrometer is a non-destructive, non-contact, remote method that determines resonant frequencies, operational deflection shapes and material parameters for modal analysis. Combining simulated results with real experimental data allows a highly precise calculation of mechanical properties and can be used to predict service times for newly designed materials.

Surface Metrology of Thin-Film Solar Cells
Laser structuring (or micro-machining) of current thin-film solar cells can be used to remove parts of the silicon layer in order to create a serial connection of single cells within a module. The topography of such laser processed structures, to analyze large-scale silicon removal or the ablation caused by a single laser pulse, can be easily and precisely measured with a Polytec surface metrology measurement system.

NIR for Identifying Plastics
Polymers display characteristic spectra. Therefore, identifying PE, PET, PP, PS, and so on is another area of application for NIR technology. High measurement speed, as well as confidence in identification, are the basis for industrial applications in sorting and recycling facilities. During the production of polymers, quick and easy quality assurance regarding water content, for example, is made possible by NIR spectroscopy.

Process Control of Biogas Plants
To achieve high efficiency and stability in biogas plants, reliable and precise measurement techniques are required as well as automated process monitoring. NIR probes can be used for process control because various process parameters can be quantified directly in the reaction vessel. Optimal production efficiency can be achieved by monitoring and controlling concentrations.
