摘　　要：讲述了热释电红外焦平面阵列的工作原理以及驱动信号的重要作用,并举例说明了32 0×2 4 0热释电红外焦平面阵列驱动电路的要求。分析了利用VH DL 语言对该阵列驱动信号编程的思路。设计完成后成功地对其进行了计算机模拟仿真。实验结果证明了用VHDL 程序设计电路的有效性。The operation principle of pyroelectric IRFPA and the important function of driving circuit are described, and the demand of driving circuit of 320×240 pyroelectric IRFPA as a example is explained. Meanwhile, the programming idea of using VHDL for the driving signal of this array is analyzed. Especially, the computer simulation after the design is achieved successfully. Experimental results proved that it can be effective to design the circuit by VHDL.
