空间目标探测中常常遇到极微弱光回波的探测问题,望远镜接收到的光信号仅有很少的光子数,甚至单光子.我们把单光子探测器运用在空间目标探测中,一方面光纤接收方式具有若干潜在优势,另一方面由于目前所用的单光子探测器的光纤接收模式的限制,决定了在空间目标的单光子探测中应用光纤接收方式.对于回波的光纤接收方式的研究将有力促进空间目标单光子探测技术的发展.
Space target detection often encountered very weak optical echo detection, the optical signal received by the telescope only a small number of photons, or even single-photon. We use single-photon detectors in the space target detection, on the one hand optical fiber The receiving mode has several potential advantages, on the other hand, due to the limitation of the optical receiving mode of the single-photon detector used currently, it is determined that the optical receiving mode is applied to the single-photon detection of the space target. Effectively promote the development of space target single photon detection technology.
