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.
