Laser Doppler Vibrometer (Laser Vibrometer) Has Obvious Advantages And Wide Range Of Applications, And The Global Market Is Expanding Gradually.

Laser Doppler Vibrometer (LDVM) has the advantages of non-contact measurement, long-distance measurement, high resolution, fast measurement speed, wide bandwidth, strong anti-jamming, real-time output signal and so on.
Laser Doppler Vibrometer, abbreviated as Laser Vibrometer, or LDV in English, is an instrument that utilizes the laser Doppler effect to measure the vibration of an object, and can measure parameters such as velocity, displacement, acceleration, and rotational speed, with a measurement accuracy of nanometer level.
Laser Doppler Vibrometer works on the principle that the laser emits polarized light, which is divided into two beams: measurement light and reference light. The measurement light irradiates the surface of the sample, the sample vibrates, the surface reflects the laser light to produce a Doppler shift, and collects the reflected light, which converges with the reference light to produce an interference signal, which carries the vibration information of the sample, and the vibration amplitude and frequency of the sample can be obtained through the detection and analysis.
The report shows that the laser Doppler vibrometer has the advantages of non-contact measurement, long-distance measurement, high resolution, fast measurement speed, wide bandwidth, strong anti-jamming, real-time output signal, etc. It does not require mass loading, which can meet the needs of micro-device detection that can not have additional mass influence, and can be used in harsh environments such as high temperature, high pressure, corrosion, radiation, and so on, as it can measure the large-sized components without the need for surface treatment.
Laser Doppler vibrometer can be widely used in electronics, instrumentation, automobiles, industrial equipment, wind power generation, new materials, medicine, construction, bridges, railroads, petroleum, nuclear industry, aerospace, scientific research and other fields, sensors, microelectromechanical, data memory, nano-materials, engines, drilling rigs, etc., and the realization of the model analysis, online monitoring, quality inspection, structural flaw detection, heart vibration measurement, bone crack monitoring and other functions. measurement, bone crack monitoring and other functions.
At this stage, the global laser Doppler vibrometer market is small, but is gradually expanding.In 2023, the global laser Doppler vibrometer market size was approximately $143 million; it is expected that the global laser Doppler vibrometer market will continue to rise at a CAGR of 3.4% from 2023-2029; and it is expected that the global laser Doppler vibrometer market size will grow to $175 billion dollars.
Globally, laser Doppler vibrometer manufacturers mainly include OptoMet (Germany), Polytec (Germany), MAUL-THEET (Germany), Julight (Italy), OMS (U.S.A.), MetroLaser (U.S.A.), Ono (ONO SOKKI) (Japan), Graphtec (Japan), HoloBright (Singapore), Sunny Optical (China), and so on. etc.
China's economy continues to develop, in order to meet the needs of various industries testing, the government's attention to laser Doppler vibrometer is increasing. The Ministry of Science and Technology released the 2023 national key research and development plan "basic research conditions and major scientific instruments and equipment research and development" key special proposed the development of independent intellectual property rights, stable and reliable quality, core components localization of the long-distance laser Doppler vibration tester, to achieve the application of the aircraft, rockets, airships, civil engineering, construction, and other fields. This will promote the development of China's laser Doppler vibration tester. This will promote China's laser Doppler vibration tester industry to enhance the competitive strength.
