激光夜视仪的研制

Development of Laser Night Vision Instrument

摘要: 激光红外夜视技术以其成像清晰、背景反差好等优点越来越受到人们的关注。本文设计了一款集光学、机械与电路于一体的激光夜视系统，采用输出功率为3 W、波长为850 nm的激光作为照明光源，激光经可调焦光学系统整形，照射到目标，其漫反射光被CCD接收，经过信号处理电路在显示器上成像。该装置整体高度约为20 cm，长度约为24 cm，重量约为0.75 kg，在不同距离和不同的激光辅助照明条件下进行了激光夜视仪的成像效果实验，结果显示激光夜视仪清晰成像的距离约为10 m~65 m。该系统适于夜间进行侦察、观察、瞄准、车辆驾驶和其它战场作业。

Abstract: Laser infrared night vision technology has attracted more and more attention due to its clear im-aging and good background contrast. This article designed a laser night vision system that inte-grates optics, machinery and circuits, using 3 W output power and the laser with a wavelength of 850 nm as an illumination source, and its diffuse light is received by the CCD when the laser is shaped by a focusable optical system to shine to the target, then, the signal processing circuit im-aging on the display. The overall height of the device is about 20 cm, the length is about 24 cm, and the weight is about 0.75 kg. The experiments of laser night vision imaging were performed at dif-ferent distances and different laser-assisted lighting conditions. The result shows that the clear imaging distance of the laser night vision is about 10 - 65 m. The system is suitable for nighttime reconnaissance, observation, sighting, vehicle driving and other battlefield operations.
