Frontiers of Information Technology & Electronic Engineering 2024, Volume 25, Issue 5,   Pages 755-762 doi: 10.1631/FITEE.2400011

Abstract: Event cameras, characterized by their low latency, large dynamic range, and extremely high temporal resolution, have recently received increasing attention. These features make them particularly well-suited for virtual/augmented reality (VR/AR) applications. To facilitate the development of three-dimensional (3D) perception and navigation algorithms in VR/AR applications using event cameras, we introduce the Stereo Event camera dataset for Virtual and Augmented Reality (SEVAR), which comprises a wide variety of head-mounted indoor sequences, including scenarios with rapid motion and a large dynamic range. We present the first comprehensive set of VR/AR datasets captured with an event-based stereo camera, a regular stereo camera at 30 Hz, and an inertial measurement unit at 1000 Hz. The camera placement, field of view (FoV), and resolution match those of the head-mounted device, such as Meta Quest Pro. All sensors are time-synchronized in the hardware. Ground truth poses captured by a motion capture system are also available for trajectory evaluation. The sequences include several common scenarios, and cover the specific challenges targeted by event cameras. The dataset can be found at .

Passive mode-locked Er-doped fiber laser pulse generation based on titanium disulfide saturable absorber Research Articles

Xinxin Shang, Linguang Guo, Huanian Zhang, Dengwang Li, Qingyang Yue,huanian_zhang@163.com,qingyangyue@sdnu.edu.cn

Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 5,   Pages 615-766 doi: 10.1631/FITEE.2000341

Abstract: In this study, (TiS) polyvinyl alcohol (PVA) film-type (SA) is synthesized with a modulation depth of 5.08% and a saturable intensity of 10.62 MW/cm by liquid-phase exfoliation and spin-coating methods. Since TiS-based SA has a strong nonlinear saturable absorption property, two types of optical soliton were observed in a mode-locked Er-doped . When the pump power was raised to 67.3 mW, a conventional mode-locked pulse train with a repetition rate of 1.716 MHz and a pulse width of 6.57 ps was generated, and the output spectrum centered at 1556.98 nm and 0.466 nm spectral width with obvious Kelly sidebands was obtained. Another type of mode-locked pulse train with the maximum output power of 3.92 mW and pulse energy of 2.28 nJ at the pump power of 517.2 mW was achieved when the polarization controllers were adjusted. Since TiS-based SA has excellent nonlinear saturable absorption characteristics, broad applications in ultrafast photonic are expected.

Abstract: formed by fabricating microstructures on the substrates have two important characteristics, ultra-light mass (surface mass density < 0.1 kg/m2) and loose surface shape tolerances (surface accuracy requirements are on the order of magnitude of centimeter). Large-aperture telescopes using a membrane diffractive optical element as the primary lens have , light weight, and low cost at launch. In this paper, the research and development on space-based s are classified and summarized. First, the imaging theory and the configuration of diffractive-optics telescopes are discussed. Then, the developments in s are introduced. Finally, the development prospects for this technology used as a high-resolution space reconnaissance system in the future are summarized, and the critical and relevant work that China should carry out is put forward.
