Wireless data transmission at 20 Mb/s over 750 m distance using a single microscopic blue LED and a Single Photon Avalanche Diode detector chip

Video documentation of an optical wireless data transmission experiment between The Lighthouse, Glasgow, and the Livingstone Tower, Glasgow. The transmitter was a blue light-emitting diode (LED) with a digitally interfaced complementary metal-oxide semiconductor (CMOS) driver and placed on the viewing platform of The Lighthouse. The receiver was a CMOS single photon avalanche diode (SPAD) chip located on the top floor of the Livingstone Tower. Both, transmitter and receiver used simple lens optics of approximately 1 inch diameter. Data were transmitted error free (i.e. with a bit error rate below the detection limit of 1e-5) at a data rate of 20 Mb/s. The video contains photographic and video footage of the experiment as well as visualisations of the geographic location created in Google Earth.

本数据集为格拉斯哥灯塔（The Lighthouse）与格拉斯哥利文斯通塔楼（Livingstone Tower）之间开展的光无线数据传输实验的视频记录档案。发射端为搭载数字接口互补金属氧化物半导体（Complementary Metal-Oxide Semiconductor，CMOS）驱动电路的蓝色发光二极管（Light-emitting Diode，LED），安装于格拉斯哥灯塔的观景平台上；接收端为安装于利文斯通塔楼顶层的CMOS单光子雪崩二极管（Single Photon Avalanche Diode，SPAD）芯片。发射端与接收端均采用直径约1英寸的简易透镜光学系统。本次实验以20兆比特每秒（Mb/s）的传输速率实现了无误码数据传输，即误码率低于1e-5的检测下限。本视频包含本次实验的摄影与摄像素材，以及通过谷歌地球（Google Earth）生成的地理位置可视化内容。背景音乐来自http://www.bensound.com/royalty-free-music。感谢格拉斯哥灯塔为本次实验提供观景平台的使用权限。
