The generation and propagation dynamics of multiple optical vortices hosted in a Gaussian beam are experimentally demonstrated by use of the computer-generated holography. Fluid-like motions of the multi-vortex beam are observed owing to the helical phase
本文报道—台自制的光学投影亚微米量级微细加工用的KrF准分子激光振荡-放大系统,并对其设计和运转性能加以讨论.该系统在200Hz重复率运转时其谱线漂移小于5×10-4 nm,谱线宽度为2.3×10-8 nm,平均功率达24.4W.
Coupling characteristics of the high-polarization dualcore photonic crystal fiber with mixing air ho
A high-polarization dual-core photonic crystal fiber (PCF) with mixing air holes is designed. The full-vector finite element method and coupled-mode theory are used to investigate the birefringence, coupling length, dispersion characteristics, normalized

Nested multilayer mirrors are commonly used in X ray telescope structure to increase the collecting area. To balance the difficulty and cost of producing these mirrors, Wolter-I structures are replaced with conical Wolter-I structures, but these can lead
We demonstrate a 0.95 GHz repetition rate fully stabilized Yb:fiber frequency comb without optical amplification. Benefitting from the high mode power and high coherence, this comb achieved 35 to 42 dB signal to noise ratio on the direct heterodyne beat s
介绍了内窥镜立体成像系统的原理。本系统采用双光路立体成像技术,模拟人的双眼,从不同的角度摄取左右两幅图像。在显示系统中,采用时分制立体显示技术,通过液晶调制屏和偏振眼镜实现观察过程中的左右图像同步分离。从而使观察者产生立体感。介绍了立体内窥镜的双光路光学系统并对各种方案进行了比较分析。对该系统在微创伤外科及光电内视检测领域的应用也作了简要的介绍。
交通标志识别在驾驶辅助系统和交通安全方面发挥着重要作用。卷积神经网络在计算机视觉任务上取得了重大的突破,并在交通标志检测与识别方面取得了巨大的成功。然而,现有的识别方法通常达不到实时识别的效果。因此,提出一种改进卷积神经网络交通标志识别方法,通过加入初始模块,扩展网络结构和提出新的损失函数等多种方法来解决原始模型不擅于检测小目标的问题。在德国交通标志数据集上的仿真结果表明,与现有技术相比,提出的方
Optical frequency combs, a revolutionary light source characterized by discrete and equally spaced frequencies, are usually regarded as a cornerstone for advanced frequency metrology, precision spectroscopy, high-speed communication, distance ranging, mol
