摘　　要：介绍了一种新型的光学分幅成像仪设计方案,相比于传统的转镜式光学分幅成像仪和变像管成像仪,该系统采用光纤传光束两个端面的排列形式可变的特点实现Cranz-Schardin原理的多通道光学分幅成像,光束快速偏转可以采用电光偏转扫描或者转镜扫描实现。图像采集系统用Basler公司的16个GigE相机作为系统摄像头,采用圆环型排列的方式实现图像分幅,可同时实现16幅数字图像采集,具有大画幅,高空间分辨的优点。采用转镜扫描对分幅成像系统进行原理性实验验证。该分幅成像系统能满足诸多高速成像领域的需求。This paper introduces a present design scheme of optical framing camera. Different from traditional rotating mirror framing camera and tube camera, the framing camera achieves multichannel optical framing image based on principle of Cranz-Schardin through the flexible arrangement of the two ends of optical fiber bound. We can realize the rapid beam deflection by using a rotating mirror or an electro-optical deflector. The image acquisition system employs 16 GigE cameras of Basler company arranged in a ring to obtain 16 high-resolution digital images synchronously with large format and high spatial resolution. Experimental results have verified the principle of the framing imaging system with a rotating mirror. This framing camera can meet the requirements in many high-speed imaging applications.
