以Zn :Fe :LiNbO3作为记录介质 ,Cu :KNSBN晶体作为自泵浦位相共轭镜 ,实现双曝光实时干涉计量。用于无损检测系统中 ,测量精度高 ,误差小。Zn :Fe :LiNbO3晶体的抗光致散射能力和响应速度皆优于Fe :LiNbO3晶体。
Taking Zn: Fe: LiNbO3 as recording medium and Cu: KNSBN crystal as self-pumping conjugate mirror, real-time double exposure exposure measurement is realized. For non-destructive testing system, high accuracy, small error. The anti-photodissociation ability and response speed of Zn: Fe: LiNbO3 crystal are better than that of Fe: LiNbO3 crystal.
