摘　　要：为了高效、高质量地获得目标偏振光谱成像结果,保障目标探测精度,设计基于嵌入式技术的偏振光谱成像系统。采集偏振光谱成像模拟信号,由模数转换单元转换为数字信号,并经由最小系统单元,调用去雾算法处理成像数字信号,获得最终目标偏振光谱成像结果,经通信单元传输至人机交互单元,向用户呈现最优的目标偏振光谱成像效果。结果表明,该系统可实现目标偏振光谱成像,最终成像效果清晰,对比度较高,目标信息量丰富、细节信息清晰、噪声少,整体成像质量较高,成像过程用时较少,可满足实际目标探测中的应用需求。In order to obtain the polarization spectrum imaging results of the target efficiently and high quality,and ensure the target detection accuracy,a polarization spectrum imaging system based on embedded technology is de-signed.Collect polarization spectrum imaging analog signal,convert it into digital signal by analog-to-digital conver-sion unit,call defogging algorithm to process the imaging digital signal through the minimum system unit,and obtain the final target polarization spectrum imaging result,which is transmitted to the human-computer interaction unit through the communication unit to present the optimal target polarization spectrum imaging effect to the user.The re-sults show that the system can realize polarization spectral imaging of the target.The final imaging effect is clear,the contrast is high,the target information is rich,the detail information is clear,the noise is small,the overall imaging quality is high,and the imaging process takes less time,which can meet the application requirements in the actual tar-get detection.
