| 中文摘要: |
| 距离选通激光主动成像可在恶劣环境条件下有效克服大气后向散射和背景干扰,得到被观测目标的高对比度图像。详细分析了大气后向散射对主动成像系统的影响,阐述了距离选通成像技术高速门控成像的原理,并就构成距离选通激光主动成像系统的关键器件如光源、像增强CCD(ICCD)、接收光学系统提出了具体性能要求和选取中需遵循的依据,文章最后介绍了目前国外的研究状况及未来的发展趋势。 |
| 英文摘要: |
| Range gated laser active imaging can be effectively overcome the atmospheric back scattering and background interference in harsh environmental conditions. High contrast target image which was observed was obtained. The paper analyzes the atmospheric back scattering effect on the active imaging system, describes range gated imaging principle of high speed gated imaging, and to constituting a laser range gated active imaging system, the key devices such as light source, image intensified CCD(ICCD), receiving optical system puts forward specific performance requirements to be followed the basis in selecting. The paper finally describes the current state of foreign research and future trends. |
