Laser vibrometers are used for accurate and non-contact measurement of displacement, acceleration or velocity of vibrating bodies. Its beam is directed to the surface, and then the frequency and amplitude of its oscillations are studied due to the frequency shift of the laser beam reflected from the surface relative to the reference beam. In the next article we present a brief description of laser vibrometers.Why are mechanical vibrations measured?
Thanks to the study of mechanical vibrations, it is possible to detect the shortcomings of machines that contribute to their accelerated wear and worsen the quality of their work. Less hassle when it comes to household appliances such as an automatic washing machine or kitchen mixer. In such cases, this is due to their destruction, uncontrolled movement or repair costs. Worse, when it comes to large industrial machines or aircraft engines, it is necessary to regularly measure vibrations to assess the degree of wear of the machine and its components in order to plan its maintenance or replacement of parts.Mechanical vibration tests are also used to determine the stability of machines to vibrations occurring in the natural environment, and to control their dynamic state, as well as to determine the impact of these vibrations on humans. The latter reason is very important, since low-frequency vibrations resonate with the internal organs of a person.Types of laser vibrometers
However, some surfaces that need to be examined are inaccessible (they may be hidden, electrically active or too hot) and laser vibrometers are used to penetrate them, i.e. devices used for non-contact measurement of surface vibration. Due to the fact that the surface is tested at a distance, the vibrometer does not change the mass and force distribution of the tested object.The most reliable test results are obtained due to the correct choice of the device. There are many types of laser vibrometers available on the market, including:laser single-point vibrometers,
3D vibrometers,
scanning and 3D scanning vibrometers,
differential vibrometers,
high-speed vibrometers,
vibrometers for measuring torsional vibrations,
vibrometers for measuring microstructures,
high-frequency vibrometers,
planar vibrometers.
Vibrations are particularly undesirable when operating mechanical devices. They negatively affect both their effectiveness and the immediate environment, including the health of people who are exposed to them. Keep this in mind and regularly measure and analyze vibrations to minimize vibrations. Laser vibrometers turn out to be very useful devices, which, using the Doppler effect, allow accurate vibration tests with very low values and their rapid and accurate visualization.
