摘要
转镜式超高速成像摄影机具有大画幅、大画幅数、高空间分辨率、宽光谱波段,以及摄影频率宽广和使用可靠方便的优势,在微秒级成像领域具有重要应用,至今依然没有任何一种电子类摄影机在画幅数、摄影速度、空间分辨率和动态范围诸方面能和转镜式摄影机相匹敌。本文论述了转镜式超高速摄影技术在其信息论的拓扑、转镜动力学的探索、转镜摄影机现代设计理论和“皇冠上的珍珠”等待型分幅扫描同时成像系统研究诸方面的进展,期望能诠释中国何以能成为转镜式超高速摄影技术的强国。
The ZDF-24 half-circle waiting rotary camera,making outstanding achievements in the first atomic bomb explosion test in China,is the ground breaking work of Xi’an Institute of Optics and Precision Mechanics,Chinese Academy of Sciences to enter the world field of vision,and the cornerstone of the development of ultra-high speed rotary camera. As you know,80% of the rotating mirror ultra-high speed cameras in China are originated from Xi’an Institute of Optics and Precision Mechanics,Chinese Academy of Sciences,which is the hometown of developing the rotating mirror ultra-high speed cameras in China.The rotating mirror ultra-high speed imaging technology has the advantages of large picture,large number of pictures,high spatial resolution,wide spectral band,wide frequency and convenient operation,so rotating mirror cameras have been the mainstay of mega-frame per second imaging for decades. There is still no electronic camera that can match a film based rotary mirror camera for the combination of frame count,speed,resolution and dynamic range. This paper discusses the research progress of the topology of its information theory,an exploration of rotary mirror dynamics,the modern design theory of rotary camera and the waiting type simultaneous framing and streak imaging system,so called“the pearl in the crown”. It is expected to explain why China can become a powerful country in rotary mirror ultra-high speed photography.
