Лазерный доплеровский скоростной метр типа BG-BDL

Применение и особенности:

The BDL laser Doppler velocimeter is an optical velocity sensor used for non-contact measurement of one-dimensional surface velocity. A dual beam laser Doppler velocimetry system that uses a phase modulator to achieve frequency shift and fast Fourier transform for frequency detection, thereby achieving velocity measurement.
This laser surface velocity and length measuring instrument adopts the most advanced laser Doppler technology today, which can non-contact measure and collect velocity and length data of the measured object.
This device uses an infrared 1550 nm band light source that is safe for human eyes;
