Abstract

Abstract

The superiority of an optical vertebra transmitting device is introduced. The main factors that impact the coupling efficiency of the optical vertebra transmitting device are analyzed, and the theoretical model error curves which impact the coupling efficiency of the optical vertebra transmitting device are gained. By taking the reflection loss of an optical vertebra end face and the fiber radiation loss as the main error sources, the coupling efficiency of optical vertebra transmitting device and the impact of errors on the coupling efficiency are tested, and a calibration method using the split ratio to measure the coupling efficiency of the transmitting device is proposed; furthermore, the impact of the changing of laser output on pulse energy measuring is eliminated. Based on the testing data, the impact curve of error on the coupling efficiency is fited, then the accuracy of the theoretical model is verified by comparison with the theoretical error curve, meanwhile the coupling efficiency of the coupling device is measured to be 70.26%. Under the condition that the laser beam incident angle error is less than 5? and the fiber is swung under the tolerance in the fiber bending extent, the effect of total error on the coupling efficiency is less than 10%, which meets the allowable error of the actual project. The coupling device has been applied to practical engineering.
