摘　　要：基于LabVIEW虚拟仪器开发技术,实现实验仪器的远程控制;并结合单片机技术,控制步进电机带动偏振控制器旋转,实现实验光路偏振态的远程控制。用户通过各种Internet终端均可随时访问该平台,从而实现了实验室的全天候运作和资源的高效利用。同时,通过综合利用LabVIEW与单片机技术,可在统一平台上集成多个光纤光学实验,从而降低系统复杂度。此外,还提出并采用一种电控偏振控制器的简易方案,用于远程调整光纤偏振态,这为搭建更为复杂实验系统提供了重要技术手段。实验表明,该平台运行稳定,可有效缓解实验设备紧缺的压力。With the increasing demands on exper!mental teaching resources, remote experimental platform have attracted much attention. Remote fiber-optics experiment platform has been studied in this paper. The laboratory apparatuses can be controlled remotely based on LabVIEW technique; the stepper motor is used to rotate the polarization controller based on micro-controller technique for controlling the optical polarization states in fibers. The platform has features of flexible control, user-defined light-path, live on-site video, and automatic record of measurement data. It can be accessed by clients with various the Internet terminals within 24-hour to achieve effective utilization of lab resources. Meanwhile, It employs the combination of Labview and micro-controller techniques so that the integrating multiple fiber-optic experiments in one platform can be achieved, and it significantly reduces the implementation complexity. Besides, a simple scheme of electrically-controlled polarization controller is implemented to adjust optical polarization states in fibers. The scheme is critical to implement more complicated remote lab experiments in the future. This remote experiment platform operates stably and alleviates the scarce pressure of experimental equipment effectively by experiments.
