MODE OF DEFINITION OF SURFACE VIBRATIONS AND AN ARRANGEMENT FOR ITS REALIZATION Russian patent published in 2006 - IPC G01H9/00 G01M7/00 

FIELD: the proposed mode and the arrangement are designed for definition of the forms of surface vibrations.

SUBSTANCE: the arrangement for definition of the forms of surface vibrations has a source of light, an investigated surface with an indicator, a recorder, a source of vibrations. Such arrangement has a matrix of photoreceivers, a matrix of electronic keys, an analogue-digital transformer, a block of controlling the keys. At that the beam of light reflected from the investigated surface is optically connected with the matrix of the photoreceivers which outputs are successively connected through the first inputs of the matrix of the electronic keys , the analogue-digital transformer is connected with the input of the recorder and the outputs of the block of controlling are connected with the second matrixes of the electronic keys. At that the source of vibrations has a kinematics connection with the investigated surface.

EFFECT: expands the field of application.
