| 摘 要： | 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.

| Abstract: | The problem of detecting very weak echo often troubles the detection for the space targets. The signals which the telescopes receive are very small, even the power is equivalent of single-photon. Therefore we develop the single-photon detection for the space targets. On the one hand, receiving modes by fibers has a number of potential advantages. On the other hand, the existing single-photon detectors use the receiving modes by fibers. This determines that single-photon detection for the space targets uses ... |
