摘要: The invention relates to an apparatus (1) for non-incremental position and form measurement of moving solid bodies (7), containing a laser Doppler distance sensor (10) head is configured as miniature (30), which splits the bichromatic light bundle (37) emitted from transmitting fibre (24) in each case into two partial beam bundles (27, 28) using beam-splitting grating (26), are made superimpose location area by deflection elements (29, 40) connected downstream. A lens (32) arranged upstream (26) such that waist (33) one wavelength (λ 1 ) located volume (31) (34) other 2 downstream (31).
