Optical design of panoramic system based on distributed aperture concept

摘要: 为了改变坦克现有探测与观瞄系统低效、精确性不足等弱点，进行基于孔径分布概念的全景系统光学设计。原理是利用4个孔径大于90的物镜对360全景图像信息进行孔径分布实时采集，采集的四路图像通过内部转像系统的折转汇成一路，由一个CCD接收，提供准确和平整的全景图拼贴的图像，对系统理想情况下的发现和分清目标距离以及盲区范围进行估算，并通过光线追迹估算出系统失效探测距离。系统在57m～6.45km的工作距离内，实现全方位、实时性的观瞄与探测功能。Abstract: In order to overcome the weaknesses of observation and detection systems in tanks, such as inefficiency and inaccuracy, the design of the panoramic optical systems based on the distributed aperture concept was performed, whose principle is to implement the real-time collection of the panoramic image information covering 360space in utilizing four objectives of aperture greater than 90, integrate the collected four-path images into one path by the internal relay system, receive the image information by a CCD camera, provide the images spliced with the accurate and uniform panoramic images, estimate under ideal situation the parameters such as detection distance, recognition distance and blind spots, and then estimate the invalid detecting distance by the aid of ray tracing. Panoramic optical systems can realize the all-dimensional real-time observation and detection at the working distance of 57m～6.45km.
