Abstract

A lamellar beam is proposed and investigated. Based on the Fresnel diffraction integral, the propagation of the beam in free space has been studied. Meanwhile, the non-diffracting and self-reconstructing properties of the beam are verified through an efficient and user-friendly optical design. We built a microscopic imaging system and used the lamellar beam for illumination, obtained a 200 × 200 pixels micrograph of a 1 mm thick sample containing fluorescent beads. We obtained a micrograph with a resolution of 1 μm, which is better than using a Gaussian beam and comparable to using a Bessel beam but spent less than a third of the time it would have taken when using Bessel beam.

传播和成像特性与贝塞尔光束相似的层状光束

提出并研究了一种片状光束。基于菲涅尔衍射积分，研究了光束在自由空间中的传播。同时，通过一种高效、易用的光学设计，验证了光束的非衍射和自重构特性。我们建立了一个显微成像系统，并使用层状光束进行照明，获得了含有荧光珠的 1 毫米厚样品的 200 × 200 像素显微照片。我们获得的显微照片分辨率为 1 μm，优于使用高斯光束，与使用贝塞尔光束相当，但所用时间不到使用贝塞尔光束的三分之一。

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
