| Abstract: | A time-avarage moire information multiplication method is proposed for studing and measuring in-plane vibrational modes. By employing this technique we can obtain measuring results of higher sensitivities with gratings of lower frequencies and commodity, Its multiplication factor is 4n and the sensitivity is adjustable. |
