【摘要】 针对恶劣天气条件下普通成像设备成像距离较短、清晰度不高的缺陷,研制了一种基于距离选通同步控制技术的全天候激光成像系统,并进行了系统可视空间深度试验及目标观测的实验室和外场试验。结果表明,可视空间深度的实验值与理论值随激光脉冲宽度增大而增加,且受激光器脉宽和像增强器门宽展宽的影响,实验值略大于理论值;在漆黑的夜晚观测1 200m和4700m处的目标最小分辨率约为5cm和10cm,在薄雾条件下观测1 900m目标图像较模糊的,分辨率为20~30cm。更多还原

【Abstract】 An all-weather laser imaging system with range gated synchronization control technology is developed aiming at shorter distance and low resolution of general imaging equipment in adverse weather conditions.The working principle and system structure are introduced.The system visual space depth,laboratory and outfield imaging experiments have been done.The results show that the experimental and theoretical values of visual space depth increase with laser pulse width and the experimental values are slightly larger than theoretical ones due to the broadening of laser pulse width and image intensifier gate width.The minimum resolutions are about 5cm and 10cm when observing the target far from 1 200m and 4 700mrespectively in dark night.The target is fuzzy and the image resolution is about 20-30cm when observing the target far from 1 900min misty condition.更多还原
