In order to improve the testable ability of an aircraft-borne optoelectronic imaging system, the comprehensive testable system design is proposed for equipment fault diagnosis. The testable system is composed of three parts, an automated test system, a testable interface, and an exterior test system. A special method combining the fuzzy theory and the expert system is used to solve the problems universally existed in the present product, such as the consideration insufficiency of testable design, low automaticity, and the incomplete fault diagnosis. The experiment results show that the fault diagnosis ratio of testable system designed in equipments has been improved to 97%. It is implicated that the testable design combining the fuzzy theory with the expert system is effective.
