通过光学引导手段可有效指引登陆艇夜间快速进入登陆舰坞舱, 基于LED小发散矩形光场整形方法, 设计了半峰全宽为2.3°×1.15°的LED引导光源, 提出了基于引导光源颜色/闪烁频率的登陆艇光学对中方法, 制作了5个颜色和闪烁频率不完全相同的LED引导光源, 搭建了光学引导系统原理样机。水上实验表明, 该样机能够有效实现登陆艇光学引导系统的对中效果。

Optical guidance means is used to guide the landing boat to enter the well-dock at night effectively and quickly. According to the rectangular light field shaping method with small divergence angles, the light emitting diode (LED) guiding source with 2.3°×1.15° full width at half maximum is designed. An optical alignment method based on guiding light source colors or flicker frequency is put forward. Based on the guidance system strategy, five LED guiding sources with different colors or flicker frequencies are manufactured and the system prototype is built. Experimental results show that the prototype can effectively realize the alignment function of the landing boat optical guidance system.
