长距离红外激光照明主动成像系统研究
Research on Long-rang Laser Illuminated Active Imaging System
【摘要】 红外激光照明成像系统克服了被动热成像系统成像对比度低、作用距离短等缺点,在全天候目标探测和识别中有着广泛的应用潜力。本文阐述了主动照明成像系统的工作原理,详细分析了影响成像质量的因素及解决方法。
【Abstract】 IR laser illuminated active imaging system overcomes the shortcomings of the thermal passive imaging system in imaging contrast and detection range, the laser illuminated imaging system can be applied to aim detection and identify- ing system all-weather. The paper elaborates the work theory of the active imaging system, particularly analyzes effect fac- tor of imaging quality and solution.
