Review of reliability and quality assurance issues for space optics systems

摘要

With the increasing complexity and precision of space-based optical systems and their longer intended lives, the effects of the space environment upon optical system reliability are becoming more important. Previously neglected phenomena pose potential threats to the success of current and future missions involving optical instruments. This paper presents a review of issues related to the reliability and quality assurance of space optics systems. Descriptions of hostile environments and mechanisms of damage are presented. Methods used to harden past and present optical systems against environmental effects are surveyed and their relative efficacies are discussed. Suggestions for actions by reliability and quality assurance personnel to mitigate the risk to future missions are outlined.
