Embodiment

[0024] the following to Taking the reticle as an example, a reticle that can generate a MittagLeffler-Bessel Gaussian beam is given for a working wavelength of 532nm. Let the value of the basic topological charge of the encoding vortex phase be m=2; the basic parameters of the MittagLeffler function are as follows , , b =1, L=2, 6, 10; the basic parameters of the Bessel function are as follows . within the function The value is determined by (x,y) (The value interval from -25.6 to 25.6 is 0.1). According to the formula we can get the The transmittance distribution of the mask, figure 1 , figure 2 The intensity distribution of the mask with L being 2 and 6 is given respectively. The black part in the figure indicates that the intensity is 0, and the white part indicates that the intensity is 1. This mask with continuous light intensity distribution can be realized by a spatial light modulator , taking the LWGL532-100mW-SLM model spatial light modulator of Bei...

Abstract

A Bessel-Gaussian beam mask plate based on the Mittag-Leffler function uses the information optics principle and combines the Mittag-Leffler modulation function, the Bessel-Gaussian beam and the plane wave complex amplitude to obtain the interference light intensity graph to realize the interference recording process of the holographic principle. The interference light intensity graph is the mask plate designed for the invention. The invention has the beneficial effects that the invention provides the Bessel-Gaussian beam mask plate based on the Mittag-Leffler function, which can produce the pattern distribution of any number of optical flaps and has important application value in the fields of multi-particle capturing and the like.

Description

technical field [0001] The invention relates to the technical field of masks, in particular to a Bessel-Gaussian beam mask based on a Mittag-Leffler function. Background technique [0002] In 1987, J. Durnin proposed a free-space non-diffraction beam, that is, the Bessel beam [J.Opt.soc.Am.A, 1987, 651-654]. The optical field distribution on each plane perpendicular to the transmission direction is always the same, and the lateral distribution of the electric field intensity is concentrated, and the width of the main lobe remains unchanged during the transmission process. In addition to the characteristics of directivity, monochromaticity, high brightness and coherence of general laser beams, this beam also has the characteristics of non-diffraction. The non-diffraction characteristic means that the light field is not subjected to diffraction expansion. extensive attention of researchers. [0003] Bessel beams are just an ideal mathematical model and cannot be produced exp...
