A transducer for lateral remote displacement measurement based on grating laser Doppler effect is introduced.The direction of movement is allowed to be perpendicular to the bisector laser beams.The measuring principle of this system is based on grating Doppler effect.A differential optical sturcture is accepted.The results of experiments and theorectical analysis show that this system gives wide measurement range
high quality signals with high resolution and accuracy
and wide range of focal depth.All of these make it very useful in the practice.
