Analysis and design of data processing system based on streak tube imaging lidar

In view of features of streak tube imaging lidar (STIL), such as wide vision, high frame frequency, high spatial and time revolution, the corresponding high performance of the data processing system was demanded. By the analysis of the content and capability, the data processing system based on STIL was analyzed and designed. The structure of data processing system based on STIL was introduced, and by the detailed analysis of the content of data processing, the processing data styles including time-delayed trigger signal and streak imaging were separately studied. Then according to the demand of the system index and the contrast of different controlling methods, high precision and tuned digital time-delayed controlling sub-system based on Altera complex programmable logic device (CPLD) was designed in order to ensure every part of the system operating strictly on the timing, capture the streak imaging of the object real time and do the processing. By the contrast of different imaging system methods and the analysis of factors including the hardware cost, establishment cycle and exploitation difficulty, STIL system taking the smart camera for its core was designed. The hardware platform of data processing system based on STIL was initially built.
