动载光学成像系统影响因素分析

Influence Factor of Dynamic Optical ImagingSystem

后向散射光是影响水下成像系统成像质量和探测距离的主要因素。改变可变的辅助照明条件是减少后向散射光影响的主要办法。为了克服后向散射的影响,文中通过对影响水下成像主要因素的分析,提出一种全新的水下成像方法。此方法是以集束光光源为核心器件,构建非均匀光场,实现对水下高速运动目标的大视角、全景深、高速率观测。为水下环境特殊成像系统的研制提供理论基础。

The backward scattered light has been the major factor influencing both imaging quality and observed space . Reducing the backward scattered light influence depends mainly on changing the auxiliary light conditions .To overcome the influence of the backward scattered light ,a new imaging method is proposed through the analysis of the factors influencing the underwater imaging in this thesis .The method is mainly by constructing inhomogeneous illumination field with distribu‐tive light with central power to achieve the underwater moving target with high speed observation in wide angle ,ALL‐in‐Fo‐cus ,high‐rate and provide theoretical basis for developing special imaging system .
