Determination of Finite Amplitude Distortion by Light Diffraction
Bill D. Cook · The Journal of the Acoustical Society of America · 1961
The theory of a new method of determining the harmonic structure of a finite amplitude wave by light diffraction has recently been given [B. D. Cook, J. Acoust. Soc. Am. 32, 336 (1960)]. This method allows the computation of the amplitudes of the harmonic components of the instantaneous pressure from the measurements of the light intensities of all of the diffraction orders. Preliminary measurements and computations indicate that this method will be a valuable tool in the study of finite amplitude distortion.
