Multi-channel time-sharing multiplexing optical coupling device and using method

Abstract

The invention provides a multi-channel time-sharing multiplexing optical coupling device and a using method. The multi-channel time-sharing multiplexing optical coupling device comprises a square cavity, a square cavity cover plate, a baffle, a rotating shaft, a motor, a bearing, a bracket, a collimating mirror, a collimating mirror adapter, a one-to-many optical fiber, a filter and an optical signal receiving and converting device, the bearings are installed on the square cavity and the square cavity cover plate, the rotating shutter is locked on the rotating shaft through screws, the squarecavity cover plate and the square cavity are locked and sealed through screws and nuts, and the function of blocking stray light is achieved. The support is fixedly connected with the square cavity and the square cavity cover plate, and the collimating mirror and the collimating mirror adapter are locked and matched through threads and then locked on the square cavity and the square cavity cover plate through threads. The square cavity and the square cavity cover plate provide channel interfaces for a plurality of groups of signals, and meanwhile, a closed environment is formed in the device,so that the influence of other stray light on the signals is reduced; the rotating shutter is driven by the motor and the bearing to rotate, and a certain group of channels in the plurality of groupsof channels is selected to be opened, so that the transmission of the group of signals and the blocking of other groups of signals are realized.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a multi-channel time-division re-measurement optical coupling device and a usage method. Background technique [0002] EAST-NBI (Experimental Advanced Superconducting Tokamak-Neutral BeamInjector) spectral diagnostic system consists of three parts: DSS beam component diagnostic system, infrared thermometer monitoring system, and stray Da monitoring system. It can respectively complete the three functions of beam component measurement, tokamak high-field side beam spot center temperature monitoring and protection, and beam reionization loss monitoring and protection in the drift section of the neutral beam injector. All three systems involve the transmission of multiple sets of optical signals. [0003] At present, the transmission of multiple groups of optical signals is mainly that each group of signals is transmitted into the optical fiber through the light-receiving lens se...
