Abstract:
1. A measurement device for non-contact detection of oscillations of an object, comprising at least one laser interferometer ( 2 , 3 ), a scanning device ( 6 , 7 , 11 ), which directs a measurement beam ( 4 ) of the at least one laser interferometer ( 2 , 3 ) onto various measurement points ( 5 ) of the object ( 1 ) for generating a scanning movement, a data recording device ( 9 ), which interacts with the laser interferometer ( 2 , 3 ) and with the scanning device ( 6 , 7 , 11 ) in order to correlate oscillation data measured by the at least one laser interferometer ( 2 , 3 ) with position data of the respective measurement point ( 5 ) obtained from the scanning device ( 11 ), and an evaluation or display device ( 10 ) for position-matched evaluation or display of the oscillation data correlated with the position data, wherein the scanning device comprises a program-controlled, moving support ( 6 ), on which at least one measurement head ( 3 ) of the at least one laser interferometer is mounted and with which the at least one measurement head ( 3 ) can be moved to the various measurement points ( 5 ), wherein the scanning device ( 6 , 11 ) is programmed so that the at least one measurement head ( 3 ) of the laser interferometer moves to the individual measurement points ( 5 ) at a preselected distance to the object ( 1 ).
