摘　　要：红外焦平面阵列时序波形初始化可以控制探测器内部复位、积分、读出、帧启动、行选通等多个晶体管开关,从而实现焦平面的图像的完整读出,但这一过程效率低下,故提出了一套全新的红外焦平面阵列的时序波形驱动方案。基于Qt实现的上位机软件完成时序波形编辑功能,基于OpenVPX架构的FPGA下位机软件完成时序波形接收、解码、下发等功能。实现了对红外焦平面阵列时序信号多通道下的高精度高效率控制。Infrared focal plane array timing waveform initialization can control multiple transistor switches such as internal reset,integration,readout,frame start,row gating,etc.,so as to realize the complete readout of the image of the focal plane,but this process is inefficient.Therefore,a new set of timing waveform driving scheme of infrared focal plane array is proposed in this paper.The upper computer software based on Qt implements the function of editing the timing waveform,and the FPGA lower computer software based on the OpenVPX architecture completes the functions of receiving,decoding,and sending timing waveforms.The high-precision and high-efficiency control of the infrared focal plane array timing signal multichannel is realized.
