The test of the optical fiber gyroscope has developed gradually towards the test automation with the increase of the automation. The design process of the test software has been introduced in this paper, focusing on the functions and realization of each module, in which the turn table control module and data processing module are the key parts in the software design. The software has been designed based on the Windows platform by adopting the object oriented method to realize the functions of the turn table and gyroscope data receiving, real time data processing and curve drawing. The proposed software has made use of the existing facilities and thus can reduce the cost of the optical fiber gyroscope calibration.
