摘要 对利用条纹场照射目标以提高成像分辨率的方法进行了实验研究。条纹法提高成像分辨率的基本思想是,采用余弦条纹场照射目标,光学系统截止频率外的一部分高频分量将通过光学系统,通过对用多幅同频条纹场照射目标所获得的图像序列进行综合处理,可以获得超分辨率的图像。实验采用激光形成的干涉条纹场照射目标,共采用10幅余弦条纹场,各幅条纹场之间依次有1/10个周期的平移,对这10幅条纹场照射目标时所拍摄的图像进行综合处理,获得了分辨率提高的图像。实验结果证明了利用干涉条纹场照射目标获得超分辨率像这一方法的可行性。 With fringe fields the experiments were carried out to improve the image resolution. The illuminating field is composed of cosine fringes, then the higher frequency component beyond the cutoff of the optical system can be passed. A higher resolution image can be obtained by processing the images from fringes with the same frequency but different phases. In the experiment, a laser is used to form ten cosine fringe fields which have 1/10 period displacement, every adjacent fringe, and the captured images are integrated to get higher-resolution image. The experiment result shows the method is feasible.
