The light amplitude of a given diffraction fringe is calculated by integrating the vectorial contributions carried to a given point of the screen by the elementary light blades into which the entering rectangular light beam can be divided. The resulting vector, in addition to the relative light intensity of a fringe gives, by its phase angle, the phase shift of the light amplitude due to the ultrasonic waves, allowing to determine, e.g., the frequency modulation or the frequency shift. Some reported curves show the graphical integrating curves and the animations evidence their evolution in time for some different diffracting arrangements and the eventual amplitude modulation. A symbol is proposed to summarize the physical parameters of the experimental diffracting arrangement when the symbolism of the Bessel functions cannot be applied.","PeriodicalId":405317,"journal":{"name":"Acousto-Optics and Applications","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121065277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We also found an increasing of M with the decrease of the temperature below the 80...100 K. The maximal value of the M reaches its value at 4.2 K. The data obtained are in good agreement with previous investigations of the optical second harmonic generation.

Instead of the laminarity amplified of the seen noise is formed the moving domain with abnormal properties: its intensity increases superexponentially in the range of 2nd order in nonlinear region, and frequency of maximum of spectrum is smoothly displaced into the region of subharmonic as far as advancement along the sample. It testifies to the absence of essential mechanism from the theory. The experiments have shown, that this mechanism is connected with three-dimensionality of the process of interaction. The critical cross-section of the interaction volume is the radius of coherency of the noise flux.
