Manufacture Process Evaluation of IFOG Using Multiple-Test Data Analysis

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 318)


To control the product quality of interferometric fiber-optic gyroscope (IFOG), an integrated evaluation method of manufacture process is proposed. First, some key manufacture processes are selected: the winding and length control of fiber-optic coil, the fiber splicing operation, and the light leakage detection of IFOG light path. Second, the important test data of each key manufacture process are collected as the evaluation indexes. The test data include the winding precision, the length control precision, the splicing effect, and the light leakage intensity. Third, the classic analytic hierarchy process (AHP) technique is utilized to evaluate the manufacture process effect of IFOG. By using the proposed technique, the process quality of IFOG can be controlled effectively. Many experiment results have proved the correctness and effectiveness of our proposed method.
