Khonina","doi":"10.1364/jot.90.000236","DOIUrl":"https://doi.org/10.1364/jot.90.000236","url":null,"abstract":"Subject of study. The effect of various deviations of the helical microstructure shape and position associated with manufacturing and alignment errors on the properties of vortex beams formed in the near diffraction zone (at a distance of about a dozen wavelengths) has been studied. Aim of study. The aim is to determine the influence of different types of shape deviations and the spiral microstructure position on the formed vortex beam properties. Method. Numerical simulation was performed using the finite-difference time-domain method with both linear and nonlinear spiral phase plates, allowing the real features of the 3D structure of the element under study to be taken into account with respect to reflection and refraction on a complex surface. The height of the microrelief, the radius of the illuminating beam, and its displacement were varied in a series of numerical experiments. Main results. It was shown that 3D shape deviations from the helical microstructure, for example, nonlinearities of the relief, lead to a distortion of the vortex dependence of the phase and break the annular intensity of the formed beam. However, in this case, the overall stability of the singular beam structure is preserved, which is completely destroyed in the case of misalignment of the illuminating beam and the optical element. A change in the height of the microrelief leads to a change in both the topological charge and the shape of the beam. As for the influence of the aperture radius of the input Gaussian beam, it is possible to scale the formed vortex beams by changing the aperture radius. Misalignment in the optical system leads to the loss of the annular structure of the vortex beam and its invariant properties. Practical significance. The obtained results can be useful in applications involving adjustable optical elements, as well as microstructures formed in photosensitive media. The main reasons for the distortion of the formed beam structure include both technological inaccuracies during etching, such as the height mismatch and changes in the structure of the zones of the diffractive optical element, and alignment errors of the optical system, such as the misalignment of the illuminating beam and the optical element. It should be noted that the characteristics of the 3D optical element structure most noticeably affect the diffraction pattern in the near zone.","PeriodicalId":16597,"journal":{"name":"Journal of Optical Technology","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135517269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A method for the measurement of the refractive index using an automated autocollimating goniometric system is proposed. Aim of study. The study facilitates the precise measurement of the refractive indices of transparent solid and liquid optical materials. Method. Goniometric methods based on the measurement of angles of light refraction caused by a substance are often used to measure the refractive indices of trihedral prisms. A method to determine the refractive index via measuring the light deviation angle caused by a prism after reflection from the internal facet in the automated mode is proposed. Main results. The refractive indices of two trihedral prisms composed of different glass types, namely, N-BK7 and SF-1, measured using the proposed method and autocollimating goniometric system are presented. The measurement error did not exceed 1.5×10−4 when compared with the nominal value for these prisms at the wavelength of the radiation source of the autocollimator, thus confirming the prospect of application of this method in high-precision refractive index measurements. Practical significance. The method proposed in this study can be used to measure the refractive indices of trihedral prisms made of optically transparent materials with different apex angles using the goniometric system in an automated mode. The method can also be applied to optically transparent liquid materials located in a hollow trihedral prism.","PeriodicalId":16597,"journal":{"name":"Journal of Optical Technology","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136328786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
