Study on generating light fields with the intensity patterns characterized by different rotational rates

Abstract: Исследование формирования световых полей с различной скоростью вращения распределения интенсивности Воронцов Е.Н. и др. 158Компьютерная оптика, 2016, том 40, №2 ВведениеСветовые поля с вращающимся при распростра-нении распределением интенсивности могут быть ис-пользованы для решения различных прикладных за-дач [1][2][3][4][5]. В настоящее время одним из наиболее об-суждаемых является их применение для увеличения продольного разрешения флуоресцентных микроско-пов [4][5]. Известно, что при получении изображения… Show more

“…In the reverse situation, i.e. with the increase of the illuminating beam aperture, the portion of energy consumed for the field formation will be redistributed from the main peaks (maxima) into the ring embracing them [17]. During the calculation of the phase mask, the optimal ratio of the phase mask aperture and the width of the illuminating beam was selected, providing the formation of two separate maxima without an additional ring around them.…”

“…Some alternative methods for realization of the phase filter that generates a field rotating during propagation were also explored [14,15]. In works [16][17][18][19], based on the theory of spiral beams of light, phase masks were offered, allowing to generate two-lobe light fields with different rotation speed.…”

“…The salvation of peculiarities mentioned above leaded to the searching of methods based on using of Bessel and Laguerre-Gaussian beams. [15,16] where the dependence of rotation angle for intensity distribution of so-called "twolobed fields" were investigated in dependence on the depth of focus for spiral beams as well as influence of amplitude and phase distortions on the formation of the light field with the intensity rotation was established. [17].…”

“…The phase distortions can be caused by aberrations of the optical system, geometric parameters of the observing system and heterogeneity of the optical parameters of the medium where a light wave propagates. Usually the influence of phase distortions prevails over that of amplitude distortions.In this paper we continue the research initiated by us earlier in our work [4]. For generation of the light fields, the phase masks based on the spiral beams were used, representing a superposition of Laguerre-Gauss modes.…”
