Patent ID: 8111403

Claim:
A method for a non-contact vibration measurement of an object comprising the processing steps of: determining at least one point ( 9 ) of the object ( 8 ) to be measured; moving at least one laser interferometer ( 6 a , 6 b , 6 c ) mounted on a carrier ( 5 ) into a measuring position (M 1 ) to measure the measuring point ( 9 ) on the object ( 8 ); emitting at least one measuring beam ( 7 a , 7 b , 7 c ) of the laser interferometer ( 6 a , 6 b , 6 c ) to at least one measuring point ( 9 ) on the object ( 8 ); detecting the measuring beam ( 7 a , 7 b , 7 c ) reflected by the object ( 8 ); determining oscillation data from the emitted and reflected measuring beam ( 7 a , 7 b , 7 c ); allocating vibration data to the measuring point ( 9 ); evaluating the vibration data and displaying processed vibration data of the measuring point ( 9 ); performing at least one alignment of a position of the laser interferometer ( 6 a , 6 b , 6 c ) for at least one position of a known freely-determined point on the object ( 8 ), and preparing a coordinate transformation instruction to determine a position of the laser interferometer ( 6 a , 6 b , 6 c ) in reference to the object ( 8 ) for arbitrary measuring positions (M 1 , M 2 ) based on the alignment.
