Research on the Optimization Design Method of Reliability Enhancement Test of Fiber Optic Acousto-optic Modulator Based on Fuzzy Theory

Abstract

The main purpose of the reliability enhancement test is to expose the weakness of the components in order to improve the process structure design. The current domestic test standards are Accelerated stress test procedures for electric and electronic products, Guidance on the definition and application of high-acceleration tests for avionics and so on. However, these standards have relatively broad provisions on test conditions. The feasible test schemes are not unique that lead to different required test conditions and test costs. The emerging device fiber optical acousto-optic modulator is expensive and the test cost is high. How to choose an efficient enhanced test program is particularly important. Based on the fuzzy theory, an optimization design method for the enhancement test of the fiber-optic acousto-optic modulator is established in this paper. This paper takes the test cost-efficiency ratio as the optimization target, and uses the reliability estimation deviation and cost as the fuzzy evaluation index for optimizing and designing of the enhancement test plan. Finally, the feasibility of the method is verified by case analysis.
