衍射是一种与光的波动性质有关的现象,当传播的波遇到障碍物时就会出现。因此,波可以在振幅或相位上变换,并发生衍射。避开障碍物的波前的那些部分在彼此干涉之后形成衍射图案。在这篇综述论文中,我们讨论了非衍射光束的主题,明确贝塞尔光束。这样的光束提供了一些衍射阻力,因此在几种情况下假设是高斯光束的现象替代。贝塞尔光束有几个突出的应用,并已在商业应用中得到应用。我们讨论了基于这些宏伟光束的几个热门应用,如光学捕获,材料加工,自由空间长距离自愈光束,光学相干层析成像,超分辨率,锐聚焦,偏振变换,增加焦深,基于光学变换的双折射检测和光通信中的加密。据我们所知,在这篇评论中提出的每个主题都得到了合理的解释。
Diffraction is a phenomenon related to the wave nature of light and arises when a propagating wave comes across an obstacle. Consequently, the wave can be transformed in amplitude or phase and diffraction occurs. Those parts of the wavefront avoiding an obstacle form a diffraction pattern after interfering with each other. In this review paper, we have discussed the topic of non-diffractive beams, explicitly Bessel beams. Such beams provide some resistance to diffraction and hence are hypothetically a phenomenal alternate to Gaussian beams in several circumstances. Several outstanding applications are coined to Bessel beams and have been employed in commercial applications. We have discussed several hot applications based on these magnificent beams such as optical trapping, material processing, free-space long-distance self-healing beams, optical coherence tomography, superresolution, sharp focusing, polarization transformation, increased depth of focus, birefringence detection based on astigmatic transformed BB and encryption in optical communication. According to our knowledge, each topic presented in this review is justifiably explained.
