基于FPGA的UIRFPA图像采集系统的设计与实现
Design and Realization of Signal Sampling System for UIRFPA Based on FPGA
【摘要】 介绍了一种红外焦平面图像采集系统的设计与实现,该系统用于对非致冷红外焦平面阵列(UIRFPA)的输出信号进行采集。系统使用FPGA作为核心CPU,控制各个模块,完成信号AD采集、FIFO缓存、异步串口通信等功能。该系统稳定可靠,通用性强,已在多个红外焦平面成像系统中得到应用。
【Abstract】 A new design and realization of signal sampling system for the infrared focal plane array have been introduced.By using this system,the output signals of the uncooled infrared focal plane array(UIRFPA)can be sampled.The modules in this system are controlled by FPGA as the CPU core to complete the functions such as signal sampling by ADC,data caching by FIFO,and communicating by UART.This signal sampling system is characterized by high stabilization,and can be widely applied in other systems except for well using in UIRFPA systems.
