“…Optical fiber collimator is an important component of optical coupling device and it has very widespread application in optical communication system. Its main role is to change the outgoing beam into a parallel beam or to converge the parallel light beam into the fiber [1]. With the development of application of collimator optical communication industry, the application of optical fiber collimator continues to expand and the requirements are also constantly improved.…”

The losses of the off-axis rotary optical fiber communication system were derived from optical fiber coupling, three kinds of misalignments between optical fiber collimators (Axial separation Z0, lateral offset X0, angular tilting θ), incomplete alignment of optical fiber collimator during rotation and system tremble caused by high speed rotating. Some measures were taken to reduce the loss. The thermally expanded core fiber collimator cut down the influence of axial separation and angular tilting. The position of the optical fiber collimator on the flange was adjusted and infrared right angle prisms were installed to reduce the losses during rotation of the system. In addition, improving the precision and optimizing device of mechanical structure can increase the stability of the whole experiment platform and decrease the losses.
