Noise and Vibration

Vibration testing of mechanical systems with laser vibrometers and/or more conventional accelerometers enables discrimination between good and faulty products and hence the analysis of vibration signals can be used for quality control on production lines. Normally, different manufacturing defects show different kinds of noise and vibration.
The nature of the problem is quite complex and requires the combination of advanced sensor technology and highly sophisticated data analysis techniques. Typical test stations employ advanced techniques of Pattern Recognition integrated into a complete system of data acquisition and signal processing. Complete and profound test on the final products is an essential requirement to obtain the necessary information for an adequate control of the production process.
