Diffraction of Light by Two Adjacent Parallel Ultrasonic Beams
For ultrasonics of longer wavelengths, it is shown that the diffraction of light caused by a fundamental tone and its n
th adjacent harmonic is the same as the diffraction caused by the superposition of the various ultrasonic components. If the wavelengths are smaller,
the diffraction of light is treated by taking the fundamental tone and its adjacent second harmonic. In choosing a range of ultrasonic wavelengths, for which diffraction orders higher than the second cannot occur, the NOA-method is applied.
Numerical calculations are performed for the intensities, and by means of graphs, comparisons are made with the results obtained in the diffraction of light caused by superposed ultrasonics.
