摘　　要：根据目视助航灯具光源特性和灯具检测存在的问题,介绍了一种基于线阵CCD的检测助航灯具出射光强分布的系统;系统以线阵CCD为光电探测元件采集出射光束各个方向的光信号,再由数据采集系统转化、实时采集并传输到上位机进行处理;通过寻找并优化相关的插值算法,对系统检测得到的数据进行数据处理,最终绘制光束的等光强曲线并求解得到出射角的范围;实验证明:通过检测系统得到的数据经算法求解后得到的结果,与测试标准进行对比,验证出该检测系统的可行性以及优化后算法的优越性,能满足测量的实际需要。For light--emitting characteristics of navigation light and the problem of light--detecting, a novel system based on linear CCD to detect intensity distribution of the navigation light was proposed. In the system, Linear CCD as detector elements was used for collecting signals intensity for each direction, and then the collected data was transformed and real--time transmitted to the host computer for process ing. By finding and optimizing the associated interpolation algorithm, and processing the data, finally it can perform data processing, respectively drawing equivalency light intensity curve and solving range of effluence angle. , By processing the data collected by the detection system, comparing the final results with the relevant standards, the experimental result show the metering system is feasible and superiority of optimizing validation algorithms, meeting the actual needs of the measurement.
