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.
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.
