Title: Elastic-wave generating method
Inventor: YAMANAKA ICHIJI
IPC: G01N29/00
Filed: 1992-12-18
Abstract: PURPOSE:To provide a elastic-wave generating method which can generate an elastic wave having a large amplitude, can control the emitting direction of the elastic wave and does not damage a body under test. CONSTITUTION:Two laser beams 1 and 2 whose frequencies are slightly different are emitted and crossed on a body 3 under test. Thus, interferencef fringes which are scanned at a high speed are generated. The distortion distribution having the same intervals as the intervals of the interference fringes is formed on the body 3 by the thermoelastic effect caused by light absorption or the electrostriction effect of light casued by an electric field. The distortion distribution is fluctuated at the same frequency as the frequency difference of the laser beams 1, 2. Therefore, the elastic wave emitted from the distortion distribution is emitted so as to have a strong directivity in the direction at an angle given by the inverse sine of the ratio of the sound speed of the elastic wave to the scanning speed of the fringes with respect to the normal on the body under test.
