文摘	近年来,关联成像成为光学成像领域的前沿和热点研究之一,它是一种新型的成像技术,具有广泛的应用价值和前景。偏振探测技术可以提升系统探测识别能力,且具有对不同材质物体的分类能力。将关联成像技术与偏振探测技术相结合,固定探测端偏振配置,使用Hadamard模式照明散斑,对照明散斑进行分时偏振调制,搭建了前向调制偏振关联成像系统。利用该系统对含有多材质物体的场景进行了偏振探测成像实验,利用探测信号与照明散斑计算出了场景的强度和偏振信息。使用演化压缩采样复原技术,在不同采样率下对场景信息进行了复原,在12.5%的采样率下获取了场景清晰的强度和偏振信息。
其他语种文摘	Correlated imaging was a new type of imaging technology, with great application value and promising prospect, which has recently become a hotspot and one of the frontiers of optical imaging researches. Polarization detecting method can improve system's ability of object detection and recognition, and categorize detected objects based on its materials. By combining correlated imaging with polarization detection, a correlated imaging system was built based on forward modulated polarization, which utilized fixed probe side polarization configuration and used Hadamard mode speckles modulated by time-shared polarization method to illuminate scenes. The system was used to carry out the polarization detection imaging experiments for the scenes with multi-material objects. The intensity and polarized images of scenes were retrieved using the correlation between the detected intensities and illumination speckles. Using evolutionary compressed sampling restoration techniques, the information of scenes was reconstructed under different sampling ratios. The clear images of the intensity and polarization are obtained under the sampling ratio of 12.5%.
